The client was first released as MSN Messenger Service on July 22, 1999, and was marketed under the MSN brand until 2005, when it was rebranded under the [[Windows Live]] name.

== Development of Windows Live Messenger ==
===Version 8.0===
====Beta 1====


Following its acquisition of [[Skype Technologies]] in May 2011, Microsoft added interoperability between [[Skype]] and [[Microsoft account]]s, allowing Skype—which had features unique to its platform and a wider user base—to communicate with Windows Live Messenger contacts. In 2013, the product was discontinued, and Microsoft began cutting service to existing clients. It remained active in China for another 18 months and ceased operations there on October 31, 2014.
The first beta was released on [[December 13]] [[2005]]<ref name="Release dates for each Messenger version" />. It remained online and usable for about a month until an auto-update feature forced one to install Beta 2, rendering this version obsolete. Major changes and additions include:


In 2018, a free version of [[Microsoft Teams]] became available after years as a component of an [[Microsoft 365|Office 365]] subscription. Teams inherited the [[Microsoft account|Microsoft accounts]] architecture, allowing users to invite contacts from the discontinued services, MSN Messenger and [[Skype]].
*Offline messaging introduced.
*Option to change the color theme of the windows. The default color (for this version only) was set to orange.
*Send and search boxes were put into different rounded boxes in the text area.
*Word wheel search box in the main window was introduced.
*Contact list was modified. When hovering your mouse over a contact, more of the contact's details show up in a yellow box.


==History==
Known bugs within this version include the offline conversation feature: although still advertised in the yellow bar at the top of the conversation box, it is useless to anyone who had not received an invitation (i.e., downloaded it from another site).<ref>[http://messengersays.spaces.live.com/blog/cns!5B410F7FD930829E!1609.entry Windows Live Messenger 8.0 Beta 1 blog entry]</ref>


===MSN Messenger 1.0–7.5 (1999–2005)===
====Beta 2====
[[File:MSN Messenger 1.0.png|thumb|upright|MSN Messenger 1.0]]


Before the product was renamed Windows Live Messenger, it was named "MSN Messenger" from 1999 to 2006. During that time, Microsoft released seven major versions as follows.
The second beta was released on [[February 26]] [[2006]]<ref name="Release dates for each Messenger version" />. The overall theme of this version was improved, fixing and improving several smaller places in the program. This version has become obsolete, forcing users to update the program. Major changes and additions include:
The first version of MSN Messenger Service, version 1.0 (1.0.0863), was released July 22, 1999. It included only basic features, such as plain text messaging and a simplistic contact list.<ref>Majid, Akbar (June 29, 2009).

America Online continually tried to block Microsoft from having access to their service until eventually the feature was removed, and it has not re-surfaced in any later versions of the software.<ref>{{cite web|url=http://www.news.com/2100-1023-228960.html|archive-url=https://archive.today/20120526215641/http://www.news.com/2100-1023-228960.html|url-status=dead|archive-date=May 26, 2012|title=AOL blocks Microsoft Net messaging|publisher=CNET News.com}}</ref> AOL did this by exploiting a buffer overflow bug in AIM, which causes it to execute a bit of machine code sent by the server. When this code runs, it determines if the client is AIM and sends a message back to verify the client.<ref>{{Cite web |url=http://www.geoffchappell.com/notes/security/aim/index.htm |title=America Online Exploits Bug In Own Software |access-date=July 4, 2012 |archive-date=July 20, 2012 |archive-url=https://web.archive.org/web/20120720215723/http://www.geoffchappell.com/notes/security/aim/index.htm |url-status=live }}</ref> Since then, the software has only allowed connections to its own service, requiring a [[Microsoft account|Windows Live ID]] (.NET Passport at that time) account to connect.
Microsoft released the first major update, version 2.0 (2.0.0083), on November 16, 1999. It included a rotating advertising banner and the ability to customize the appearance of the chat window. It came as an install option for [[Windows Me]]. This version was followed the next year by version 3.0 (3.0.0080), which was released May 29, 2000. It included file transfers and PC-to-PC and PC-to-phone audio capabilities with [[Net2Phone]] and Callserve,<ref>{{cite web|title=Callserve registers over a half million Microsoft Messenger users|url=http://www.m2.com/m2/web/story.php/2002376C7E22F65FFE2D80256BEC0045AD29|url-status=usurped|archive-url=https://web.archive.org/web/20161124025444/http://www.m2.com/m2/web/story.php/2002376C7E22F65FFE2D80256BEC0045AD29|archive-date=November 24, 2016|access-date=November 23, 2016|publisher=m2.com}}</ref> two of the larger [[Voice over IP|VoIP]] providers.<ref>Crouch, Cameron (July 20, 2000).

Along with the release of [[Windows XP]] came version 4.6 of MSN Messenger, on October 23, 2001. It included major changes to the user interface, the ability to group contacts, and support for voice conversations.<ref>{{cite web |url-status=dead |last1=Keizer |first1=Gregg |date=February 26, 2002 |url=http://www.zdnet.com.au/reviews/software/internet/soa/Instant-Messaging-Road-Test/0,139023437,120263712-6,00.htm |title=Instant Messaging Road-Test – Messenger 4.6 |archive-url=https://web.archive.org/web/20090904064620/http://www.zdnet.com.au/reviews/software/internet/soa/Instant-Messaging-Road-Test/0,139023437,120263712-6,00.htm |archive-date=September 4, 2009 |website=[[ZDNet]]}}</ref> In this version, the client software was renamed from "MSN Messenger Service" to just "MSN Messenger", while the underlying service became known as "[[Microsoft Messenger service|.NET Messenger Service]]". This version was only compatible with [[Windows 95]], [[Windows 98|98]], [[Windows ME|ME]], [[Windows NT 4.0|NT 4.0]], and [[Windows 2000|2000]], because Microsoft provided a scaled-down new program for [[Windows XP]], called [[Windows Messenger]]. Version 5.0 of MSN Messenger was released on October 24, 2002.

Version 6.0 of MSN Messenger was released July 17, 2003. MSN Messenger 6.0 was a major overhaul of the whole platform, upgrading its simple text-based interface to include customizable elements such as emoticons, personalized avatars, and backgrounds. An update, version 6.1, focused on improvements to the conversation window, enabling users to hide the window frame and menu bar, and also the ability to change the theme color. The theme color could be set differently for each user. Another update, version 6.2, was released April 22, 2004, and it was the last version of the MSN Messenger 6 series. The most notable changes were a dedicated ''Mobile'' group for mobile contacts, a connection troubleshooter, and the ''Launch Site'' feature was renamed to ''Fun & Games''.{{Citation needed|date=December 2023}}
====Beta 3====


MSN Messenger received a major upgrade to version 7.0 on April 7, 2005. This version brought [[Wink (animated file)|wink]] features that were previously only available in [[threedegrees]].

Additionally, a new Voice Clips feature allowed users to hold down F2 and record a message for a maximum of 15 seconds and send it to the recipient. The window for conversations was changed slightly with an added video button. This version also introduced the [[Windows Installer]] for its auto-update feature.<ref>{{cite web|url=http://msdn.microsoft.com/library/default.asp?url=/library/en-us/msi/setup/patching.asp|title=Patching|publisher=Microsoft Developer Network |url-status=dead |archive-url=https://web.archive.org/web/20090903222743/http://msdn.microsoft.com/en-us/library/aa370578(VS.85).aspx |archive-date=September 3, 2009 }}</ref>

Milestone 3 also brings a new "[[Windows Live Groups|Groups]]" feature that allows users to create a continuous group conversation between select contacts, newly redesigned status icons which now resemble small gems rather than the previous "Messenger Buddy" icons, a new default "Favorites" category in which you can place your favorite contacts for easy access to them, a new Photo Sharing utility that allows contacts to quickly and easily browse photos together, and a "What's New" section at the bottom of the contact list to outline recent contact updates. Display pictures have been moved over to the left side of conversation windows, and new colorful borders appear around display pictures to display the current status of that contact.

The new software features a revamped interface which brings the "What's new" section of Windows Live to the new "social pane", similar to the way a social networking site presents updates. Among the new features are tabbed conversations, a redesign of the old emoticons, integration of [[Bing (search engine)|Bing]] results, built-in [[Windows Live Video Messages|video message]] support, HD video chat, in-line commenting of social updates, a new social photo viewer that supports commenting (for Facebook and SkyDrive photos), badges support, synchronized status updates, availability by categories, as well as integration with [[Facebook chat]]. However, several features had also been removed from the previous version, such as the removal of display names, handwriting tool,<ref>{{Citation | title = LiveSide | contribution = Wave 4: What's New in Messenger? | url = http://www.liveside.net/main/archive/2010/04/28/wave-4-what-s-new-in-messenger.aspx | date = April 28, 2010 | access-date = May 17, 2010 | archive-date = May 3, 2010 | archive-url = https://web.archive.org/web/20100503223735/http://www.liveside.net/main/archive/2010/04/28/wave-4-what-s-new-in-messenger.aspx | url-status = dead }}</ref> one-way webcam requests and import/export of instant messaging contacts feature. The "Wave 4" release of Windows Live Essentials, which includes Messenger, also dropped compatibility with [[Windows XP]] and only runs on [[Windows Vista]] or [[Windows 7]].<ref>{{Citation | url = http://windowsteamblog.com/blogs/windowslive/archive/2010/04/21/getting-ready-for-windows-live-wave-4.aspx | contribution = Getting ready for Windows Live Wave 4 | title = Windows team | type = blog | publisher = Microsoft | access-date = April 20, 2012 | archive-date = May 3, 2010 | archive-url = https://web.archive.org/web/20100503140505/http://windowsteamblog.com/blogs/windowslive/archive/2010/04/21/getting-ready-for-windows-live-wave-4.aspx | url-status = live }}</ref>
This beta does not include the device manager included in 8.0, meaning the Live Messenger phone does not install, a window will open with a title saying 'please install device manager' and showing MSN today. It is not known if the device manager will be included in the final release, although it is expected to be, due to the cost of the phone.


The new Windows Live Messenger for the [[iOS (Apple)|iOS]] became available on the [[App Store (iOS)|App Store]] on June 21, 2010, in addition to other mobile versions of Windows Live Messenger for [[Windows Phone]], [[BlackBerry]], and [[Symbian]] mobile platforms.<ref>{{cite web |url=https://gizmodo.com/5525910/windows-live-messenger-iphone-app-almost-looks-better-than-desktop-version |title=Windows Live Messenger iPhone App Almost Looks Better Than Desktop Version |author=Rosa Golijan |date=April 27, 2010 |publisher=[[Gizmodo]] |access-date=April 26, 2010 |archive-date=April 29, 2010 |archive-url=https://web.archive.org/web/20100429081157/http://gizmodo.com/5525910/windows-live-messenger-iphone-app-almost-looks-better-than-desktop-version |url-status=live }}</ref>
== Features new to Windows Live Messenger==
To the features available in [[MSN Messenger]], Windows Live Messenger adds the following:
===Sharing folders===
The ''Sharing Folder'' feature of Windows Live Messenger is an alternative to the "[[Friend-to-friend|direct transfer]]" method of file distribution. When a user wants to deliver a file to another person on his or her [[contact list]], the "sharing folder" window appears, which is an individualized representation of all previously shared items.


On June 24, 2010, a public beta of Windows Live Messenger Wave 4 was released as part of the new Windows Live Essentials beta.<ref>{{cite web |url=http://windowslivepreview.com/messenger/ |title=Windows Live Preview Messenger Download |date=June 24, 2010 |publisher=[[Microsoft]] |access-date=June 24, 2010 |archive-date=June 22, 2010 |archive-url=https://web.archive.org/web/20100622003804/http://windowslivepreview.com/messenger/ |url-status=dead }}</ref> A "beta refresh" of Windows Live Messenger Wave 4 was released on August 17, 2010, as part of an upgraded Windows Live Essentials beta.<ref>{{cite web |url=http://windowsteamblog.com/windows_live/b/windowslive/archive/2010/08/17/windows-live-essentials-2011-beta-refresh.aspx |title=Windows Live Essentials 2011 beta refresh |first=Chris |last=Jones |date=August 17, 2010 |publisher=[[Microsoft]] |access-date=August 17, 2010 |archive-date=August 19, 2010 |archive-url=https://web.archive.org/web/20100819194853/http://windowsteamblog.com/windows_live/b/windowslive/archive/2010/08/17/windows-live-essentials-2011-beta-refresh.aspx |url-status=live }}</ref> The final version of Windows Live Messenger 2011 (Wave 4) was released on September 30, 2010.<ref>{{cite web |url = http://windowsteamblog.com/windows_live/b/windowslive/archive/2010/09/30/windows-live-essentials-2011-available-for-download-now.aspx |title = Windows Live Essentials 2011 available for download now |first = Chris |last = Jones |date = September 30, 2010 |access-date = February 15, 2011 |archive-date = April 8, 2011 |archive-url = https://web.archive.org/web/20110408225537/http://windowsteamblog.com/windows_live/b/windowslive/archive/2010/09/30/windows-live-essentials-2011-available-for-download-now.aspx |url-status = live }}</ref> On the same date, a version of Windows Live Messenger for [[Zune HD]] also became available.<ref>{{cite web|last1=LeBlanc|first1=Brandon|title=Windows Live Messenger for the Zune HD|url=http://blogs.windows.com/bloggingwindows/2010/10/01/windows-live-messenger-for-the-zune-hd/|website=Blogging Windows|publisher=[[Microsoft]]|access-date=August 31, 2014|date=October 1, 2010|archive-date=September 3, 2014|archive-url=https://web.archive.org/web/20140903112247/http://blogs.windows.com/bloggingwindows/2010/10/01/windows-live-messenger-for-the-zune-hd/|url-status=live}}</ref><ref>{{cite web|last1=Warren|first1=Tom|title=Windows Live Messenger for Zune HD released|url=http://www.neowin.net/news/windows-live-messenger-for-zune-hd-released|website=[[Neowin]]|access-date=August 31, 2014|date=October 1, 2010|archive-date=September 4, 2014|archive-url=https://web.archive.org/web/20140904210645/http://www.neowin.net/news/windows-live-messenger-for-zune-hd-released|url-status=live}}</ref>
When files are added to the "sharing folder" for that particular person, the file will automatically be transferred to the corresponding computer when they are online. This means that the folder is literally "shared" between two computers. If a user deletes a file, for example, the file will also be deleted from the corresponding computer's shared folder.


On June 14, 2012, Microsoft made the update from 2009 to 2011 mandatory for those using Windows Vista or 7. 2009 continues to be usable for those still running XP.<ref>{{cite web |first=Rudi |last=R. |url=http://answers.microsoft.com/en-us/windowslive/forum/messenger-wlinstall/mandatory-update-to-windows-live-essentials-is-now/0816b1b7-71ff-44f7-8d74-52505bbbf290 |title=Mandatory Update to Windows Live Essentials is now available |work=Microsoft Community |publisher=Microsoft |date=June 15, 2012 |access-date=April 22, 2012 |archive-date=June 19, 2012 |archive-url=https://web.archive.org/web/20120619201620/http://answers.microsoft.com/en-us/windowslive/forum/messenger-wlinstall/mandatory-update-to-windows-live-essentials-is-now/0816b1b7-71ff-44f7-8d74-52505bbbf290 |url-status=live }}</ref> This can be circumvented by running Windows Live Messenger in Windows XP compatibility mode, thus making it believe it is running on Windows XP.<ref>{{cite web|title=How to Disable Windows Live Messenger 2009 Force to Update|url=http://www.webtlk.com/2011/01/25/how-to-disable-windows-live-messenger-2009-force-to-update/|work=Web Talk|access-date=April 22, 2013|date=January 25, 2011|archive-date=May 10, 2013|archive-url=https://web.archive.org/web/20130510162750/http://www.webtlk.com/2011/01/25/how-to-disable-windows-live-messenger-2009-force-to-update/|url-status=live}}</ref>
To minimize risk of virus-infected transfers, the "sharing folder" feature is bundled with an [[anti-virus]] program. The "sharing folder" feature can only be used on computers with [[NTFS]]-formatted [[hard disk]]s.


On August 7, 2012, Microsoft delivered a new version of the [[Windows Essentials]] 2012 suite, which includes Windows Live Messenger 2012.<ref>{{cite web|title=Windows Essentials 2012 released, comes with new Movie Maker and Photo Gallery|url=http://www.winbeta.org/news/windows-essentials-2012-released-comes-new-movie-maker-and-photo-gallery|website=WinBeta|date=August 7, 2012|access-date=August 31, 2014|archive-date=September 3, 2014|archive-url=https://web.archive.org/web/20140903072442/http://www.winbeta.org/news/windows-essentials-2012-released-comes-new-movie-maker-and-photo-gallery|url-status=live}}</ref><ref>{{cite web|last1=Serea|first1=Razvan|title=Windows Essentials 2012 (16.4.3503.0728) released|url=http://www.neowin.net/news/windows-essentials-2012-16435030728-released|website=[[Neowin]]|access-date=August 31, 2014|date=August 8, 2012|archive-date=September 1, 2014|archive-url=https://web.archive.org/web/20140901102850/http://www.neowin.net/news/windows-essentials-2012-16435030728-released|url-status=live}}</ref>
=== PC-to-phone calls ===
{{main|Windows Live Call}}


===Discontinuation and legacy===
In addition to PC-to-PC calls that have been supported in previous versions, Windows Live Messenger now supports PC-to-phone calls with [[Windows Live Call]]. In the US, this feature is supported by [[Verizon]], branded as "Verizon Web Calling". [[Orange SA|Orange]] France also has a similar service. This feature is only available in selected countries, including the US, the UK (Verizon planning to end service in [[August]] [[2008]]), France, Germany, the Netherlands, Austria, Ireland, Finland, Belgium, Spain, and Italy.
On November 6, 2012, Microsoft announced that Messenger and [[Skype]] services would merge in the first quarter of 2013. According to [[Tony Bates]] (president of Skype Division at the time), Messenger users could sign into Skype using their [[Microsoft account]]s, access their Messenger contacts and communicate as usual.<ref>{{cite web|last=Wilhelm|first=Alex|title=Confirmed: Microsoft to retire its Messenger IM service in Q1 2013, moving 100M+ users to Skype in single act|url=https://thenextweb.com/microsoft/2012/11/06/microsoft-to-retire-its-messenger-im-service-in-q1-2013-moving-100mm-users-to-skype-in-single-move/|work=The Next Web|access-date=April 13, 2013|date=November 6, 2012|archive-date=March 8, 2013|archive-url=https://web.archive.org/web/20130308100940/http://thenextweb.com/microsoft/2012/11/06/microsoft-to-retire-its-messenger-im-service-in-q1-2013-moving-100mm-users-to-skype-in-single-move/|url-status=live}}</ref><ref>{{cite web|last=Bates|first=Tony|title=Talk to your Messenger Contacts on Skype|url=http://blogs.skype.com/2012/11/06/skypewlm/#fbid=g2svObsNezQ|work=Skype Blog|publisher=Microsoft|access-date=April 13, 2013|date=November 6, 2012|archive-date=April 27, 2013|archive-url=https://web.archive.org/web/20130427070242/http://blogs.skype.com/2012/11/06/skypewlm/#fbid=g2svObsNezQ|url-status=live}}</ref> On January 8, 2013, Microsoft emailed Messenger users and informed them that with the exception of [[mainland China]], the Messenger service would stop working on March 15, 2013, and users would not be able to sign in.<ref name="Protalinski">{{cite web|last=Protalinski|first=Emil|title=Microsoft confirms Messenger will be retired and users migrated to Skype on March 15|url=https://thenextweb.com/microsoft/2013/01/09/microsoft-emails-messenger-users-to-let-them-know-the-service-is-retiring-on-march-15-and-to-upgrade-to-skype/|work=The Next Web|access-date=April 13, 2013|date=January 9, 2013|archive-date=April 14, 2013|archive-url=https://web.archive.org/web/20130414132856/http://thenextweb.com/microsoft/2013/01/09/microsoft-emails-messenger-users-to-let-them-know-the-service-is-retiring-on-march-15-and-to-upgrade-to-skype/|url-status=live}}</ref>

On [[October 13]], [[2005]], Yahoo! and Microsoft announced plans to introduce interoperability between their two messengers,<ref>[http://www.vnunet.com/vnunet/news/2143773/yahoo-msn-marry-messengers Yahoo and MSN marry IM services, vnunet.com, [[2005-10-13]]]</ref> creating the second largest instant messenger user base worldwide: 40 percent of all users. The announcement comes after years of third-party interoperability success (most notably, [[Trillian (instant messenger)|Trillian]], [[Pidgin (software)|Pidgin]]) and criticisms from [[Google]] that the major instant messengers were locking their networks. Microsoft has also had talks with [[AOL]] in an attempt to introduce further interoperability, but so far, AOL seems unwilling to participate.


In 2017 a number of developers managed to [[Reverse engineering|reverse engineer]] the Messenger protocol and designed custom servers that make the MSN/Windows Live Messenger functional again. The service is now provided under the name ''Escargot MSN''.<ref>{{Cite web |title=Escargot {{!}} MSN Messenger and Windows Live Messenger |url=https://escargot.chat/ |access-date=2023-10-24 |website=escargot.chat}}</ref><ref>{{Cite web |last=updated |first=Jez Corden last |date=2021-03-23 |title=An homage to MSN Messenger, and simpler times |url=https://www.windowscentral.com/homage-msn-messenger-and-simpler-times |access-date=2023-10-24 |website=Windows Central |language=en}}</ref><ref>{{Cite web |last=Man |first=Doritos |date=2020-02-08 |title=MSN Messenger is Back! |url=https://datahorde.org/msn-messenger-is-back/ |access-date=2023-10-24 |website=Data Horde |language=en-US}}</ref>
Interoperability between Yahoo! and Windows Live Messenger was launched [[12 July]], 2006.<ref>[http://www.bigblueball.com/forums/msn-messenger-news/36522-yahoo-microsoft-im-interoperability-arrives.html Yahoo Interoperability Arrives]</ref><ref>[http://www.microsoft.com/presspass/press/2006/jul06/07-12IMInteropPR.mspx Microsoft Press Release: Yahoo! and Microsoft Bridge Global Instant Messaging Communities]</ref> This allows Yahoo! and Windows Live Messenger users to chat (using text or voice) to each other without the need to create an account on the other service, provided both contacts use the latest versions of the clients. However, if a user uses an older or third-party client, they will appear offline to the users on the other network.


=== Offline messaging ===
== Features ==
In addition to its basic functionality and general capability as an instant messaging client, the latest version of Windows Live Messenger offered the following features:
Unlike previous versions, one can send messages to contacts who are offline; they will receive the messages once they come online.


=== Album Viewer ===
Additionally, one can start conversations even when his or her status is set to ''Appear Offline'', similar to behaviour in [[Yahoo! Messenger]] and [[ICQ]]. If talking to someone who has an older MSN Messenger client, they will lose the ability to talk to you after a short period of no activity, due to their client thinking you are offline. As Windows Live Messenger has now been made available on several phones, a new trend has appeared where people send messages over Windows Live Messenger to each other through an Internet connection, rather than [[SMS]] messages.
{{See also|Windows Photo Gallery}}
Windows Live Messenger's album viewer is based on [[Windows Photo Gallery]] and provides users a photo viewing experience for photo albums shared via [[File system|SkyDrive]] and Facebook. The album viewer is interactive and supports full screen and slideshow modes, as well as viewing and uploading comments on Facebook and SkyDrive albums. It also supports people tagging for SkyDrive. The album viewer closely resembles the [[Microsoft Silverlight]] counterpart for web photo albums present on SkyDrive.{{Citation needed|date=December 2023}}

=== Appear offline to individuals or categories ===
Windows Live Messenger allows users to appear offline to particular individual contacts, as well as to an entire category within Windows Live Messenger, while appearing online to other contacts.{{Citation needed|date=December 2023}}

This is a recent feature of Windows Live Messenger 2011, and is a departure from the previous versions of Windows Live Messenger, where blocking a contact would prevent the "blockee" from sending the user any messages to the "blocker". With the "appear offline to" configuration currently implemented, "hidden from" users can still send "offline messages" to the target.<ref>{{Citation | url = http://menthix.net/windows-live-messenger-2010-beta-review/ | title = Windows Live Messenger 2010 Beta | type = review | publisher = Menthix | access-date = April 20, 2012 | archive-date = March 3, 2012 | archive-url = https://web.archive.org/web/20120303222819/http://menthix.net/windows-live-messenger-2010-beta-review/ | url-status = dead }}</ref>

=== Social networks integration ===
Users can connect services such as [[Facebook]], [[Myspace|MySpace]] and [[LinkedIn]] using [[Windows Live Profile]], and display their contact's Messenger social updates within the "Full view" of Windows Live Messenger. Users can also post status updates and photos directly to the connected services within Windows Live Messenger. Additionally, Messenger also imports all contacts from the connected services and integrates with [[Facebook Chat]] (via the [[XMPP]] protocol) for instant messaging support with users on Facebook.{{Citation needed|date=December 2023}}

=== Offline messaging ===
One can send messages to contacts who are offline; they will receive the messages once they come online. Additionally, a user can start conversations even when their status is set to ''Appear Offline'' in Windows Live Messenger 2009 or before.{{Citation needed|date=December 2023}}

===Messenger Companion===
=== '''"i’m"''' initiative ===
[[File:Windows Live Messenger Companion 2011.png|thumb|Windows Live Messenger Companion]]
The '''i’m''' initiative is a program Microsoft launched in March 2007, that connects the user with nine organizations dedicated to social causes through Windows Live Messenger. Every time someone has a conversation using '''i’m''', Microsoft Corp. shares a portion of the program's advertising revenue with the organization of the user's choice. Only conversations that are sent to and/or received in the [[United States]] are recognized. There is no set cap on the amount donated to each organization. The more ''i’m'' conversations the user has, the more money goes to one of the nine causes. Each participating organization is guaranteed a minimum donation of $100,000 during the first year of the program. There is currently no end date for the program.<ref>[http://im.live.com/Messenger/IM/About/Press/PDFs/imInitiative.pdf]</ref> The '''i’m''' initiative only works with WLM version 8.1 and 8.5.
'''Windows Live Messenger Companion''' was an add-in for [[Windows Internet Explorer]] that detects when a user is on a website that one of their friends has shared content from and surfaces that update so that the user can instantly view what their friends have shared and leave a comment to the shared content on [[Windows Live]].<ref>[http://www.windowslivepreview.com/messenger/new/#benefit_1 What's New in Messenger: Windows Live Reviewer's Guide] {{Webarchive|url=https://web.archive.org/web/20100509032649/http://windowslivepreview.com/messenger/new/#benefit_1 |date=May 9, 2010 }}. Windowslivepreview.com. Retrieved on April 20, 2012.</ref> The service utilizes [[Windows Live ID]] and integrates tightly with Windows Live Messenger to obtain the user's contact list and their shared contents. The features of Windows Live Messenger Companion include:
*Sharing links to web pages with the user's friends on Windows Live within the web browser
*See links to web pages the user's friends have shared
*Add comments to the links the user's friends have shared
Windows Live Messenger Companion was made available as part of [[Windows Live Essentials]] 2011. However, Microsoft discontinued Messenger Companion in its newer [[Windows Essentials]] 2012 suite.{{Citation needed|date=December 2023}}


=== Xbox 360 ===
===Protocol===
{{Main|Microsoft Notification Protocol}}
Windows Live Messenger support was included in the [[Xbox 360]] Spring 2007 [[dashboard update]] released on [[May 9]], [[2007]].<ref>[http://www.xbox.com/en-US/community/news/2007/0408-im.htm News on Spring 2007 Update] from xbox.com</ref> Unofficially, it is known as Windows Live Messenger 360.


Windows Live Messenger used the [[Microsoft Notification Protocol]] (MSNP) over [[Transmission Control Protocol|TCP]] (and optionally over [[HTTP]] to deal with [[Proxy server|proxies]]) to connect to [[Microsoft Messenger service]]—a service offered on [[TCP and UDP port|port]] 1863 of "messenger.hotmail.com."{{Citation needed|date=December 2023}}
Those using Windows Live Messenger are able to see the [[Gamertags]] of [[friends]] logged into [[Xbox Live]], including the [[game]] they are playing. Xbox 360 users can chat in-game (or while watching a movie). Although only text chat is supported, [[Microsoft]] has suggested that voice and video chatting may come in a future update.


The protocol is not completely secret; Microsoft disclosed version 2 (MSNP2) to developers in 1999 in an [[Internet Draft]],<ref>[http://tools.ietf.org/html/draft-movva-msn-messenger-protocol draft-movva-msn-messenger-protocol-00 – MSN Messenger Service 1.0 Protocol]. Tools.ietf.org (August 31, 1999). Retrieved on April 20, 2012.</ref> but never released versions 8 or higher to the public. The Messenger service servers currently only accept protocol versions from 8 and higher, so the syntax of new commands sent from versions 8 and higher is only known by using [[packet sniffer]]s like [[Wireshark]]. This has been an easy task because – in comparison to many other modern instant messaging protocols, such as [[Extensible Messaging and Presence Protocol|XMPP]] – the Microsoft Notification Protocol does not provide any [[encryption]] and everything can be captured easily using packet sniffers. The lack of proper encryption also makes wiretapping friend lists and personal conversations a trivial task, especially in unencrypted public [[Wi-Fi]] networks.{{Citation needed|date=December 2023}}
Also to coincide with the arrival of the integration of Windows Live Messenger with Xbox Live, Microsoft released a new Xbox 360 keyboard adaptor called [[Xbox 360 Chatpad]] for easier text input. The keyboard device attaches to the standard Xbox 360 controller through the headphone jack and features a [[QWERTY|QWERTY-style]] key layout with 47 keys, although any USB keyboard will work just as well with an Xbox 360.


=== Content filtering ===
As of December 4, 2007 a child account can now use Windows Live Messenger on Xbox Live.
The content of users' messages is filtered on server side of the client. For example, the user can not send the links to [[The Pirate Bay]]'s pages neither from the Windows Live Messenger, nor through other clients supporting the protocol. However, links to other [[Peer-to-peer|P2P networks]] are allowed.<ref>{{cite web |url=http://torrentfreak.com/microsoft-censors-pirate-bay-links-in-windows-live-messenger-120324/ |title=Microsoft Censors Pirate Bay Links in Windows Live Messenger |first=Ernesto |last=Van Der Sar |work=[[TorrentFreak]] |date=March 24, 2012 |access-date=April 1, 2012 |quote=Whatever Microsoft's reason for monitoring private conversations and then swallowing Pirate Bay links, the Redmond-based company's censorship policies are not very consistent.

=== S60 Platform ===
=== "i'm" initiative ===
The '''i'm''' initiative was a program Microsoft launched in March 2007, that connects the user with ten organizations dedicated to social causes through Windows Live Messenger, only for conversations sent or received in the USA. Every time someone had a conversation using '''i'm''', Microsoft Corp. shared a portion of the program's advertising revenue with the organization of the user's choice. There was no set cap on the amount donated to each organization. The more ''i'm'' conversations the user had, the more money went to one of the ten causes. Each participating organization was guaranteed a minimum donation of $100,000 during the first year of the program. The '''i'm''' initiative worked with version 8.1 and above.{{Citation needed|date=December 2023}}

* The status "On the phone" from the previous version was renamed to "In a call" due to the addition of [[Windows Live Call]].
[[File:Windows Live Messenger Mobile screenshot.png|thumb|Messenger Mobile WAP version]]
* Nicknames of individual contacts can be customized to appear differently from what the contact has set.
Versions were developed for [[Windows]], [[Xbox 360]], [[Mac OS X]] (later under the name Microsoft Messenger for Mac), [[BlackBerry OS]], [[iOS]], [[Java ME]], [[S60 (software platform)|S60]] on [[Symbian OS]] 9.x, [[MSN TV]], [[Zune HD]],<ref>{{cite web |date=October 3, 2010 |title=Metro inspired Windows Live Messenger caught on Video |url=http://www.1800pocketpc.com/2010/10/03/metro-inspired-windows-live-messenger-caught-on-video.html |archive-url=https://web.archive.org/web/20110906024530/http://www.1800pocketpc.com/metro-inspired-windows-live-messenger-caught-on-video/15618/ |archive-date=6 September 2011 |work=1800PocketPC}}</ref> [[Windows Phone]], [[Windows Mobile]] and [[Windows CE]].{{Citation needed|date=December 2023}}
* Messages from contacts can now be time-stamped.
* Windows Live Messenger has the ability to turn off prepending of contact names if the same person writes multiple messages. If the same contact writes more than one message, the contact name will be displayed for only the first message. However, if messages are timestamped, and the time changes, the contact's name will be displayed with the new time.
* A [[color scheme]] can be chosen for the entire application, including the status window, and not just the conversation windows. A paint brush menu is situated below the personal message box in Windows Live Messenger, to facilitate choosing colors.
* [[Microsoft Passport]] has been replaced with [[Windows Live ID]].
* ''Word wheel'' search within the contact list.
* Beginning with version 8.1, one's display picture and personal message are stored on the server, so wherever one signs in, the display picture and message will still appear. However, all computers must have version 8.1 or later for the feature to work.


'''Messenger Mobile''' (formerly named '''Windows Live Messenger Mobile''') was the version of Messenger that was aimed to be used on mobile devices over a cellular data plan or Wi-Fi (if supported by the phone). There was also a [[Wireless Application Protocol|WAP]]-compatible version that may be used on any mobile device, and also specific client versions designed for [[Windows Mobile]], [[iOS]], [[BlackBerry]] and [[Nokia]] [[Series 60]] devices.{{Citation needed|date=December 2023}}
== Protocol ==


===Windows Mobile===
Windows Live Messenger uses the [[Microsoft Notification Protocol]] (MSNP) over [[Transmission Control Protocol|TCP]] (and optionally over [[HTTP]] to deal with [[Proxy server|proxies]]) to connect to the .NET Messenger Service—a service offered on [[TCP and UDP port|port]] 1863 of messenger.hotmail.com. Its current version is 15 (MSNP15), used by Windows Live Messenger and other third-party clients. MSNP15 introduces a different authentication mechanism. The protocol is not completely secret; Microsoft disclosed version 2 (MSNP2) to developers in 1999 in an [[Internet Draft]], but never released versions 8, 9, 10, 11, 12, 13, or 14 to the public. .NET Messenger Service servers currently only accept protocol versions from 8 and on, so the syntax of new commands from versions 8 through 14 is only known by using [[packet sniffer]]s like [[Wireshark]].
A client version of Windows Live Messenger Mobile was a part of client application named "Windows Live for Windows Mobile" included with the [[Windows Mobile]] 6 operating system. It was included on both Windows Mobile 6 smartphone edition (non-touch screen phones) and professional (touch screen phones). Among other features you could send voice-clips (max 10 seconds), pictures & emoticons.{{Citation needed|date=December 2023}}


== Competition ==
=== Xbox ===
Windows Live Messenger support was included in the [[Xbox 360]] spring 2007 dashboard update released on May 9, 2007.<ref>[http://www.mywhatsappstatus.com/2014/12/instant-messaging-comes-to-xbox-360.html News on Spring 2007 Update] {{Webarchive|url=https://web.archive.org/web/20141209001439/http://www.mywhatsappstatus.com/2014/12/instant-messaging-comes-to-xbox-360.html |date=December 9, 2014 }} from Xbox.com.</ref> It was known as Xbox Live Messenger.<ref>[http://support.xbox.com/support/en/us/xbox360/kb.aspx?ID=937407 Support page] {{Webarchive|url=https://web.archive.org/web/20200926111926/https://support.xbox.com/support/en/us/xbox360/kb.aspx?ID=937407 |date=September 26, 2020 }} from Xbox.com. Retrieved on December 16, 2009.</ref>


Those using Windows Live Messenger were able to see the [[Gamertags]] of friends logged into [[Xbox Live]], including the games that they were playing. Xbox 360 users could chat in-game or while watching a movie. Although only text chat was supported, Microsoft suggested that voice and video chatting may come in a future update.{{Citation needed|date=December 2009}} Support for child accounts was added in December 2007.{{Citation needed|date=December 2023}}
The most significant rivals of Windows Live Messenger are [[AOL Instant Messenger|AIM]] and [[ICQ]] (both from [[AOL]]), [[Skype]], [[Trillian (instant messenger)|Trillian]], [[Pidgin (software)|Pidgin]] (formerly Gaim), [[aMSN]] and [[List of Jabber client software|Jabber based clients]] including [[Google Talk]].


To coincide with the arrival of the integration of Windows Live Messenger with Xbox Live, Microsoft released a new Xbox 360 keyboard adapter called the [[Xbox 360 Messenger Kit]] for easier text input. The keyboard device attaches to the standard Xbox 360 controller through the headphone jack and features a [[QWERTY|QWERTY-style]] key layout with 47 backlit keys. However, any USB keyboard is also compatible with the Xbox 360.{{Citation needed|date=December 2023}}
In China [[QQ]] is the predominant instant messenger. Although usage outside of China is minimal, domestic usage is in excess of 226 million users.{{Fact|date=June 2007}} However with MSN Messenger's recent entrance into the Chinese Market, QQ's popularity has been significantly curtailed. Currently MSN Messenger holds approximately 17 percent of the Chinese market share.


Microsoft also announced on June 14, 2010, that users on Xbox LIVE with the controller-free [[Kinect]] could have real-time video conversations with Windows Live Messenger contacts. This feature was enabled at launch.<ref>-[http://windowsteamblog.com/windows_live/b/windowslive/archive/2010/06/14/connecting-windows-live-messenger-and-xbox-live.aspx Inside Windows Live: Connecting Windows Live Messenger and Xbox LIVE] {{Webarchive|url=https://web.archive.org/web/20100618053732/http://windowsteamblog.com/windows_live/b/windowslive/archive/2010/06/14/connecting-windows-live-messenger-and-xbox-live.aspx |date=June 18, 2010 }}</ref>
In Mexico, Framecode used to be one of the most popular instant messenging clients, but recently it has faded into obscurity.


=== MSN TV (WebTV) ===
[[Gadu-Gadu]] remains the most popular IM in [[Poland]], with over 6 million users online daily. Recently, however, it has slowly been giving way to [[Skype]].
[[File:Msntv2_messenger_convo.jpg|thumb|right|MSN Messenger on MSN TV 2]]
Starting in the summer of 2000, the Microsoft-owned web access product [[MSN TV]] (then known as WebTV) introduced a software upgrade for users of its internet terminals that added a basic messaging client among other features. The messaging client was designed to work with the [[Microsoft Messenger service]] and was simply named '''MSN Messenger'''.<ref>{{cite web |url=http://net4tv.com/Voice/Story.cfm?storyID=2370 |last1=Davenport |first1=Dexter |title=WebTV Details Upgrade: Real G2, IM, Windows Media, More |website=Net4TV Voice |access-date=26 July 2021 |archive-url=https://web.archive.org/web/20020227203150/http://net4tv.com/Voice/Story.cfm?storyID=2370 |archive-date=2002-02-27}}</ref> The client for the original WebTV/MSN TV internet terminals supported basic presence, plain text messages (no graphical emoticons), and buddy lists, with the overall WebTV/MSN TV service hosting services for users to add, remove, or block Messenger contacts and manage their Messenger settings. Windows Live Messenger support was later added to the MSN TV 2, introducing a new UI to fit the rest of the MSN TV 2's interface and support for graphical emotions. It's believed these clients still worked up until the discontinuation of the MSN TV service in September 2013.{{Citation needed|date=December 2023}}


Although WebTV was also available in Japan well before the Summer 2000 upgrade was introduced in the US, it does not appear that Japanese WebTV users ever received this Messenger feature.{{Citation needed|date=December 2023}}
== Third-party Add-ins ==


=== Mac ===
Some add-ins are available to modify Live Messenger, enable hidden features, or extend capabilities. They include:
'''Microsoft Messenger for Mac''' (previously '''MSN Messenger for Mac''') was the official [[macOS|Mac OS X]] [[instant messaging]] client for use with [[Microsoft Messenger service]], developed by the [[Macintosh Business Unit]], a division of [[Microsoft]]. Its feature list was limited in comparison to that of its counterpart Windows Live Messenger; the client lacked a number of features that its Windows counterpart contained.{{Citation needed|date=December 2023}}


The versions 3.x and later of Microsoft Messenger for Mac featured new [[Aqua (GUI)|Aqua]] graphics, whereas version 2.x and below have graphics similar to [[Windows Messenger]] 4.0. Versions 5.x used the [[brushed metal (interface)|brushed metal]] theme.{{Citation needed|date=December 2023}}

With the release of Microsoft Messenger for Mac 7.0, Microsoft has discontinued the client's support for older versions of their Corporate messaging systems (such as [[Live Communications Server 2005]]). The latest version to support these older systems is Version 6.0.3, which is still available for download on the Microsoft website.{{Citation needed|date=December 2023}}


Webcam and audio support was delayed due to Windows Live Messenger's webcam and audio engine being reworked, which meant that the Mac version had to wait until this was complete in order for both platform releases to function correctly.{{Citation needed|date=December 2023}}
Windows Live Messenger (along with other networks such as Yahoo! Messenger and AOL Instant Messenger) is often used as a conduit or "vector" for delivering malicious software such as spyware, viruses, worms, and trojans to unsuspecting computer users. The two methods used by hackers to deliver malware over the IM vector are (1) sending a file transfer with a virus-infected file, and (2) delivering a message with socially engineered content containing a web address (URL) containing active malicious code. Viruses and worms with colorful names such as W32.Yalove or Troj/Msnfake-L have been identified as targeting users of the Windows Live Messenger network (and the former MSN Messenger network) over the past few years.


===iOS===
The threat of infection by these two methods is substantial and growing. The [http://www.imsecuritycenter.com IM Security Center], a collaboration between security companies and corporations, has tracked attacks over IM since 2003 and shows well over 1000 distinct attacks over the public IM networks. The first half of 2007 saw an 84% increase in IM attacks over the first half of 2006. While IM-specific attacks remain a small percentage of overall virus and malware threats, the continued growth in usage of IM, along with the rapid adoption of IM in the workplace (See [[Instant Messaging]]) make IM an attractive vector for hackers, and both individuals and companies must take precautions to avoid infection.
The Windows Live Messenger for [[iOS]] client supported receiving of instant messaging notifications even when the application closed, and allowed Multiple Points of Presence (MPOP) such that a user can be signed into multiple locations at the same time. Photos and albums could also be uploaded from the mobile devices onto [[Windows Live Photos]], based on [[Windows Live SkyDrive|SkyDrive]], and the application allowed simple image editing capabilities and people tagging within the photos. The application also supported the "Messenger social" feed on [[Windows Live Profile]], allowing users to view and comment on the social updates and activities of their contacts on Windows Live, as well as those on Facebook, MySpace and [[LinkedIn]] once these social networks had been connected to Windows Live as a "Service".{{Citation needed|date=December 2023}}


===Java ME===
The most common method of delivering a malicious payload is the use of social engineering to construct a message that appears to be coming from a contact on the recipient's contact list. A socially engineered message is one that is written in a friendly, informal manner, that could easily be mistaken as coming from a friend. The message usually will say something like "Click here to see pics of me from vacation!" or "Is this you?" with a web address -- known as a "poison URL" -- for the recipient to click. Upon clicking the web address, the recipient is connected to a website containing active content, which is immediately downloaded to the recipient's computer. In most cases, the payload contains an installer, a number of hidden files containing text, and code which causes the same socially engineered message with poison URL to be sent to every contact on the contact list. When the message is sent to all contacts, the cycle starts again, as each contact believes they are receiving a message from a trusted friend. In this manner, IM-borne malware is capable of propagating very rapidly through company and external networks.


====Nokia Series 40====
Worms and viruses are discovered on a regular basis by security companies, particularly by the three companies with network-certified [[Instant messaging manager| IM-specific security products]], Akonix Systems, FaceTime Communications, and Symantec. According to IM security researchers at Akonix, the mean number of new threats per month identified during the period January 2006 through August 2007 is 34, with a high of 88 in October 2006, and a standard deviation of 19.<ref>The IM Security Center, www.imsecuritycenter.com</ref>
The Windows Live Messenger Mobile client came as a [[Java ME]] mobile application pre-loaded on devices such as Nokia 7610, Nokia 7510, Nokia 7210, Nokia 6700c, Nokia 6600s, Nokia 6303c, Nokia 6260s, Nokia 5220, Nokia 5130XM, Nokia 3720c, Nokia 3710f, Nokia, 3600s, Nokia 2730c, Nokia 2700c, Nokia 5530, Nokia 6303c and Nokia X3.{{Citation needed|date=December 2023}}

===Symbian===
On [[September 12]], [[2007]], the [http://messengersays.spaces.live.com/ Windows Live Messenger blog] posted an entry that reported of a security vulnerability discovered in versions of Messenger older than 8.1. The vulnerability "could allow remote code execution when a user accepts a webcam or video chat invitation from an attacker. An attacker who successfully exploited this vulnerability could take complete control of the affected system." This led to an auto-update being released to all older versions. Versions running on [[Windows 2000]] and below were required to update to a new version of [[MSN Messenger|MSN Messenger 7.0]], and versions running on [[Windows XP]] and above were required to update to [[#Version 8.1|Windows Live Messenger 8.1]].<ref>[http://messengersays.spaces.live.com/blog/cns!5B410F7FD930829E!29167.entry Windows Live Messenger blog: Upgrading to 8.1]</ref>.

MSN Messenger (also known colloquially simply as MSN[2][3]), later rebranded as Windows Live Messenger, was a cross-platform instant-messaging client developed by Microsoft.[4] It connected to the now-discontinued Microsoft Messenger service and, in later versions, was compatible with Yahoo! Messenger and Facebook Messenger. The service was discontinued in 2013 and was replaced by Skype.

The client was first released as MSN Messenger Service on July 22, 1999, and was marketed under the MSN brand until 2005, when it was rebranded under the Windows Live name. It has since been officially known by the latter name, although its first name remained in common use.[5][6] In June 2009, Microsoft reported the service attracted over 330 million active users each month, placing it among the most widely used instant-messaging clients in the world.[7]

Following its acquisition of Skype Technologies in May 2011, Microsoft added interoperability between Skype and Microsoft accounts, allowing Skype—which had features unique to its platform and a wider user base—to communicate with Windows Live Messenger contacts. In 2013, the product was discontinued, and Microsoft began cutting service to existing clients. It remained active in China for another 18 months and ceased operations there on October 31, 2014.

In 2018, a free version of Microsoft Teams became available after years as a component of an Office 365 subscription. Teams inherited the Microsoft accounts architecture, allowing users to invite contacts from the discontinued services, MSN Messenger and Skype.

History[edit]

MSN Messenger 1.0–7.5 (1999–2005)[edit]

MSN Messenger 1.0

Before the product was renamed Windows Live Messenger, it was named "MSN Messenger" from 1999 to 2006. During that time, Microsoft released seven major versions as follows. The first version of MSN Messenger Service, version 1.0 (1.0.0863), was released July 22, 1999. It included only basic features, such as plain text messaging and a simplistic contact list.[8] When it was first released, it featured support for access to America Online's AIM network. America Online continually tried to block Microsoft from having access to their service until eventually the feature was removed, and it has not re-surfaced in any later versions of the software.[9] AOL did this by exploiting a buffer overflow bug in AIM, which causes it to execute a bit of machine code sent by the server. When this code runs, it determines if the client is AIM and sends a message back to verify the client.[10] Since then, the software has only allowed connections to its own service, requiring a Windows Live ID (.NET Passport at that time) account to connect. Microsoft released the first major update, version 2.0 (2.0.0083), on November 16, 1999. It included a rotating advertising banner and the ability to customize the appearance of the chat window. It came as an install option for Windows Me. This version was followed the next year by version 3.0 (3.0.0080), which was released May 29, 2000. It included file transfers and PC-to-PC and PC-to-phone audio capabilities with Net2Phone and Callserve,[11] two of the larger VoIP providers.[12]

Along with the release of Windows XP came version 4.6 of MSN Messenger, on October 23, 2001. It included major changes to the user interface, the ability to group contacts, and support for voice conversations.[13] In this version, the client software was renamed from "MSN Messenger Service" to just "MSN Messenger", while the underlying service became known as ".NET Messenger Service". This version was only compatible with Windows 95, 98, ME, NT 4.0, and 2000, because Microsoft provided a scaled-down new program for Windows XP, called Windows Messenger. Version 5.0 of MSN Messenger was released on October 24, 2002. It was the first version that was allowed to be installed along with Windows Messenger on Windows XP.[14] It included UPnP (Universal Plug and Play) based file transfers, minor changes to the user interface artwork, and a Windows Media Player interface plug-in.[15]

Version 6.0 of MSN Messenger was released July 17, 2003. MSN Messenger 6.0 was a major overhaul of the whole platform, upgrading its simple text-based interface to include customizable elements such as emoticons, personalized avatars, and backgrounds. An update, version 6.1, focused on improvements to the conversation window, enabling users to hide the window frame and menu bar, and also the ability to change the theme color. The theme color could be set differently for each user. Another update, version 6.2, was released April 22, 2004, and it was the last version of the MSN Messenger 6 series. The most notable changes were a dedicated Mobile group for mobile contacts, a connection troubleshooter, and the Launch Site feature was renamed to Fun & Games.[citation needed]

MSN Messenger received a major upgrade to version 7.0 on April 7, 2005. This version brought wink features that were previously only available in threedegrees. This version also advertised items to sell to you including animated display pictures, emoticons and backgrounds. The contact list window style was also updated to match instant message windows. This version also introduced the Xbox Live Integration feature. This version also introduced digital ink and handwriting recognition support. It is the last version of MSN Messenger to support Windows 98, Windows Me and Windows 2000.[citation needed]

The last version of MSN Messenger before the name change, version 7.5, was released August 23, 2005. New features included the Dynamic Backgrounds feature and the "msnim" protocol handler, which allowed Web sites to provide links which automatically add a contact or start conversations. Additionally, a new Voice Clips feature allowed users to hold down F2 and record a message for a maximum of 15 seconds and send it to the recipient. The window for conversations was changed slightly with an added video button. This version also introduced the Windows Installer for its auto-update feature.[16]

Windows Live Messenger 8.0–8.5 (2005–2009)[edit]

Windows Live Messenger logo

As part of Microsoft's Windows Live effort, which rebranded many existing MSN services and programs, MSN Messenger was renamed "Windows Live Messenger" beginning with version 8.0.[citation needed]

The first beta of the newly renamed Windows Live Messenger, Beta 1, was released on December 13, 2005.[6] Major changes and additions included offline messaging, an option to change the color theme of the windows, separated send and search boxes, a word wheel search box in the main window, and additional details for contacts when hovering over their names in the contact list window.[citation needed]

The second beta of version 8.0, Beta 2, was released on February 26, 2006.[6] The overall theme of this version was improved, fixing and improving several smaller places in the program. Major changes and additions included the introduction of Windows Live Contacts, the reintroduction of single file transfer, improvements to the "Add a Contact" dialog box, improved color themes, minor changes in the conversation window, and revert of the "Busy" status icon back to the normal dash icon and a redesign of the log in page.[17]

The final beta version, Beta 3, was released on May 2, 2006.[6] Major changes and additions included new icons for the program, PC-to-phone calling, an updated look for the Windows Live Call window, a new default display picture, the Windows Live Today window, improvements to the grouping of sequential messages from each contact, Rhapsody integration in the US, and an option for sounds to be edited and/or turned off and another redesign of the log in page,[18]

Windows Live Messenger 8.0

The official release of Windows Live Messenger version 8.0 was on June 19, 2006.[6] Although no notable changes were made between Beta 3 and the final version,[19] the change from MSN Messenger to Windows Live Messenger brought some additional changes, such as customization for the nicknames of individual contacts, timestamps on messages, the ability to see a contact's name only once if the same person writes multiple messages in a row, and color schemes for the entire application. The main authentication system, Microsoft Passport Network, was replaced with Windows Live ID at the same time. A refresh to version 8.0 was released on August 10, 2006.[6] It included audio and video improvements and fixed up minor bugs.[20]

The first update to Windows Live Messenger was previewed on October 30, 2006, with the release of Beta 1 of version 8.1.[6] No major changes were made, but several minor changes were included. These include the addition of the roaming identity feature (so that the same user's display name and picture would appear on any computer), a new contact card appearance, a "recently used" list for the emoticon, wink, display picture and background menus, an SMS phone book in the main menu allowing the association and editing of a phone number to the contact and allowing text messaging to a contact, a "sign out" button, a "report abuse" option in the help menu, interoperability with Yahoo! Messenger, and improvements to user status on Windows Vista[21]

A minor update, the Windows Live Messenger 8.1 Beta 1 Refresh, was released on December 13, 2006,[6] and fixed bugs that were causing some people to be unable to sign in and others unable to see their contact list.[22]

The final version 8.1 was released on January 29, 2007.[6] No changes were made from the Beta 1 Refresh.[23] All versions of Windows Live Messenger below version 8.1 were rendered obsolete on September 12, 2007, due to a security issue identified when a user accepts a webcam or video chat invitation from an attacker.[24]

On September 12, 2007, the Windows Live Messenger blog posted a fix that resolved a security problem. It reported of a security vulnerability in versions of Messenger older than 8.1, that the released fix would resolve. This led to an auto-update being released to all older versions. Versions running on Windows 2000 and below were required to update to a new version of MSN Messenger 7.0, and versions running on Windows XP and above were required to update to Windows Live Messenger 8.1.[24]

On August 27, 2009, the Windows Live Messenger blog posted that due to a security problem, all users of versions 8.1 and newer need to update to the latest version, 14.0.8089. The mandatory upgrade requirement would be fully phased in by late October 2009 and began on September 15, 2009.[citation needed]

The first beta of Windows Live Messenger 8.5, Beta 1, was released on May 31, 2007.[6] An update was released on June 21, 2007, to test updates being installed by Microsoft Update. This version required Windows XP SP2, compared to previous versions requiring Windows XP SP1. It was the first version to be installed in a "Windows Live" folder under "Program Files", with the shortcuts placed in a "Windows Live" folder in the Start Menu.[citation needed]

Major changes and additions in Beta 1 included a new installation program in conjunction with the release of Windows Live 2.0, a new look for all of its windows that matches the aesthetic styles of Windows Vista,[25] a new "bunny" emoticon,[26] and integration with Windows Live OneCare Family Safety.[27] Beginning with this version, updates could be downloaded and installed through Microsoft Update.

The second beta of Windows Live Messenger 8.5, Beta 2, was released on September 5, 2007.[28] Several issues were fixed in Beta 2, but no significant changes were applied. Compared with the first beta, the build does not say "Beta" on the top of the window, although developers had noted that it was not the final release. The new Windows Live Installer, which is used to install Windows Live Messenger 8.5 Beta 2, does not run on Windows Server 2003.[citation needed]

The final release of Windows Live Messenger version 8.5 was released on November 6, 2007, and it introduced no major changes.[29]

Windows Live Messenger 14.0–16.4 (2009–2012)[edit]

Windows Live Messenger, c. 2011

Windows Live Messenger 2009 was originally designated version 9.0, it was later assigned the technical version number 14.0, in order to be unified with the other Windows Live programs and Microsoft Office programs.[citation needed]

In a presentation to the Georgia Institute of Technology's IEEE Student Branch, Microsoft employee Andrew Jenks reported that the Messenger team had been working on multi-person audio/video chat, and they are also attempting to create interoperability with AIM/XMPP/ICQ. There is a basic internal version that works with XMPP already.[30] However, these features were not seen in any versions of Windows Live Messenger 2009.[citation needed]

Microsoft sent an invitation to participate in the Windows Live Messenger "9" beta program to Microsoft Connect members on November 20, 2007; a week later, Microsoft began sending out emails welcoming them to the Windows Live Messenger "9" beta program for the first release, known as Beta 0.[citation needed]

A fan site for Windows Live Messenger, Mess.be, claimed to have a new build of Windows Live Messenger "9" on August 11, 2008, and published screenshots along with a brief summary of new features. The screenshots featured a new user interface design matching the "Wave 3" design in development by Microsoft. The images were later removed by the site after a DMCA notice was received.[31] The installer for the same build was leaked through private forums on August 23, 2008. It would later be discovered this build was a preview of Milestone 2, or M2.[citation needed]

News web site LiveSide published an article on September 4, 2008, with screenshots of M2 of the newly minted "Windows Live Messenger 2009", which had become version 14.0 instead of 9.0 as previously expected. LiveSide summarized its new features, including protection against messaging spam, the ability to stay signed into the application from several computers (referred to as "Multiple Points of Presence Support"), animated GIF files in the photo area, per-contact customized sounds for various user actions, and clickable URLs in the status area.[32]

Microsoft began the official beta program for Windows Live Messenger 2009 on September 17, 2008, when it released a new beta officially known as Windows Live Messenger 2009 Beta (Milestone 3, Build 14.0.5027.908), which was made available to the general public as a free download. The ability to submit feedback, however, was restricted to select participants of the Microsoft Connect closed beta program.[citation needed]

Notable changes in Milestone 3 include a new revamped and refined user interface to follow suit with the rest of the Windows Live "Wave 3" design, the ability to set a "Scene" by customizing the background image and color of the contact list, and the display of these scenes in conversation windows for improved contact identification and window management.[citation needed]

Milestone 3 also brings a new "Groups" feature that allows users to create a continuous group conversation between select contacts, newly redesigned status icons which now resemble small gems rather than the previous "Messenger Buddy" icons, a new default "Favorites" category in which you can place your favorite contacts for easy access to them, a new Photo Sharing utility that allows contacts to quickly and easily browse photos together, and a "What's New" section at the bottom of the contact list to outline recent contact updates. Display pictures have been moved over to the left side of conversation windows, and new colorful borders appear around display pictures to display the current status of that contact. Milestone 3 is the first version of Windows Live Messenger to use the standard window frame on Windows Vista in accordance with the user experience guidelines.[citation needed]

Several features were removed in version 9.0, however, such as the ability to use add-ins, the ability to transfer files when the recipient is signed in as offline, the "Be right back", "Out to lunch", and "In a call" status options,[33] the Go to my space button, the ability to adjust webcam settings during a video call, the Send button,[34] some games (depending on your localization) and integration with Windows Contacts.[35] Other features were replaced, such as Sharing Folders[36] (replaced by integration with Windows Live SkyDrive) and background sharing (replaced by the "Scene" feature).[citation needed]

On December 15, 2008, Windows Live Messenger 2009 RC (Build 14.0.8050.1202) was released together with the other Windows Live Wave 3 software applications, now renamed as Windows Live Essentials.[37] This version saw a removal of the custom sign-in sound feature however it is still possible to select a sound for other individuals, as well as changes to how the background image chosen is applied to the conversation windows. This build also included over 200 bug fixes including the "Custom Emoticon Bug" and saving of pictures when using the Photo sharing feature. On January 7, 2009, the same build was released as the final version of Windows Live Messenger 2009.[38]

The last QFE update for Wave 3 was released on May 12, 2010, and saw the removal of some features from Windows Live Messenger. Specifically, the ability to independently show only your own webcam or your contacts' webcam (one way webcam) and without an audio call is gone.[39] It is only possible to start a video call which starts the webcams of both people communicating, and which also automatically starts audio calling. Also removed is the ability to import and save/export instant messaging contacts to and from .CTT files.[40]

In late March 2010, a beta of Windows Live Essentials Wave 4 was leaked onto the internet and has since spread to various BitTorrent networks, which included a private beta build of Windows Live Messenger Wave 4. However, as the software was designed for private beta testing, non-beta testers cannot sign into this leaked build.[41]

The new software features a revamped interface which brings the "What's new" section of Windows Live to the new "social pane", similar to the way a social networking site presents updates. Among the new features are tabbed conversations, a redesign of the old emoticons, integration of Bing results, built-in video message support, HD video chat, in-line commenting of social updates, a new social photo viewer that supports commenting (for Facebook and SkyDrive photos), badges support, synchronized status updates, availability by categories, as well as integration with Facebook chat. However, several features had also been removed from the previous version, such as the removal of display names, handwriting tool,[42] one-way webcam requests and import/export of instant messaging contacts feature. The "Wave 4" release of Windows Live Essentials, which includes Messenger, also dropped compatibility with Windows XP and only runs on Windows Vista or Windows 7.[43]

The new Windows Live Messenger for the iOS became available on the App Store on June 21, 2010, in addition to other mobile versions of Windows Live Messenger for Windows Phone, BlackBerry, and Symbian mobile platforms.[44]

On June 24, 2010, a public beta of Windows Live Messenger Wave 4 was released as part of the new Windows Live Essentials beta.[45] A "beta refresh" of Windows Live Messenger Wave 4 was released on August 17, 2010, as part of an upgraded Windows Live Essentials beta.[46] The final version of Windows Live Messenger 2011 (Wave 4) was released on September 30, 2010.[47] On the same date, a version of Windows Live Messenger for Zune HD also became available.[48][49]

On June 14, 2012, Microsoft made the update from 2009 to 2011 mandatory for those using Windows Vista or 7. 2009 continues to be usable for those still running XP.[50] This can be circumvented by running Windows Live Messenger in Windows XP compatibility mode, thus making it believe it is running on Windows XP.[51]

On August 7, 2012, Microsoft delivered a new version of the Windows Essentials 2012 suite, which includes Windows Live Messenger 2012.[52][53]

Discontinuation and legacy[edit]

On November 6, 2012, Microsoft announced that Messenger and Skype services would merge in the first quarter of 2013. According to Tony Bates (president of Skype Division at the time), Messenger users could sign into Skype using their Microsoft accounts, access their Messenger contacts and communicate as usual.[54][55] On January 8, 2013, Microsoft emailed Messenger users and informed them that with the exception of mainland China, the Messenger service would stop working on March 15, 2013, and users would not be able to sign in.[56]

On February 15, 2013, ZDNet wrote the discontinuation email was only sent to one percent of Messenger users, a test group.[57] On the same day, Microsoft announced its plans to phase out Messenger: the process would start on April 8, 2013, with English users and would end on April 30, 2013; Messenger would remain available in mainland China.[58] According to ZDNet, this might only apply to the ability to sign in with Messenger client; Microsoft would keep its Messenger service running for another year.[57] "Windows Live Messenger Upgrades to Skype", as they were referred to by Microsoft, started on April 8, 2013. This transition took place language by language. Brazil was the last country to be "upgraded", on April 30.[citation needed]

Chinese Messenger users received an email from Microsoft in August 2014, containing an announcement that Messenger service in China would end on October 31, 2014; users were advised to migrate to Skype and receive free credits.[59][60]

In 2017 a number of developers managed to reverse engineer the Messenger protocol and designed custom servers that make the MSN/Windows Live Messenger functional again. The service is now provided under the name Escargot MSN.[61][62][63]

Features[edit]

In addition to its basic functionality and general capability as an instant messaging client, the latest version of Windows Live Messenger offered the following features:

Album Viewer[edit]

Windows Live Messenger's album viewer is based on Windows Photo Gallery and provides users a photo viewing experience for photo albums shared via SkyDrive and Facebook. The album viewer is interactive and supports full screen and slideshow modes, as well as viewing and uploading comments on Facebook and SkyDrive albums. It also supports people tagging for SkyDrive. The album viewer closely resembles the Microsoft Silverlight counterpart for web photo albums present on SkyDrive.[citation needed]

Appear offline to individuals or categories[edit]

Windows Live Messenger allows users to appear offline to particular individual contacts, as well as to an entire category within Windows Live Messenger, while appearing online to other contacts.[citation needed]

This is a recent feature of Windows Live Messenger 2011, and is a departure from the previous versions of Windows Live Messenger, where blocking a contact would prevent the "blockee" from sending the user any messages to the "blocker". With the "appear offline to" configuration currently implemented, "hidden from" users can still send "offline messages" to the target.[64]

Social networks integration[edit]

Users can connect services such as Facebook, MySpace and LinkedIn using Windows Live Profile, and display their contact's Messenger social updates within the "Full view" of Windows Live Messenger. Users can also post status updates and photos directly to the connected services within Windows Live Messenger. Additionally, Messenger also imports all contacts from the connected services and integrates with Facebook Chat (via the XMPP protocol) for instant messaging support with users on Facebook.[citation needed]

Offline messaging[edit]

One can send messages to contacts who are offline; they will receive the messages once they come online. Additionally, a user can start conversations even when their status is set to Appear Offline in Windows Live Messenger 2009 or before.[citation needed]

Games and applications[edit]

There are various games and applications available in Windows Live Messenger that can be accessed via the conversation window by clicking on the games icon, and challenging your friend or contact to a competition in a game, or inviting them to launch a shared external application.

Messenger Companion[edit]

Windows Live Messenger Companion

Windows Live Messenger Companion was an add-in for Windows Internet Explorer that detects when a user is on a website that one of their friends has shared content from and surfaces that update so that the user can instantly view what their friends have shared and leave a comment to the shared content on Windows Live.[65] The service utilizes Windows Live ID and integrates tightly with Windows Live Messenger to obtain the user's contact list and their shared contents. The features of Windows Live Messenger Companion include:

  • Sharing links to web pages with the user's friends on Windows Live within the web browser
  • See links to web pages the user's friends have shared
  • Add comments to the links the user's friends have shared

Windows Live Messenger Companion was made available as part of Windows Live Essentials 2011. However, Microsoft discontinued Messenger Companion in its newer Windows Essentials 2012 suite.[citation needed]

Protocol[edit]

Windows Live Messenger used the Microsoft Notification Protocol (MSNP) over TCP (and optionally over HTTP to deal with proxies) to connect to Microsoft Messenger service—a service offered on port 1863 of "messenger.hotmail.com."[citation needed]

The protocol is not completely secret; Microsoft disclosed version 2 (MSNP2) to developers in 1999 in an Internet Draft,[66] but never released versions 8 or higher to the public. The Messenger service servers currently only accept protocol versions from 8 and higher, so the syntax of new commands sent from versions 8 and higher is only known by using packet sniffers like Wireshark. This has been an easy task because – in comparison to many other modern instant messaging protocols, such as XMPP – the Microsoft Notification Protocol does not provide any encryption and everything can be captured easily using packet sniffers. The lack of proper encryption also makes wiretapping friend lists and personal conversations a trivial task, especially in unencrypted public Wi-Fi networks.[citation needed]

Content filtering[edit]

The content of users' messages is filtered on server side of the client. For example, the user can not send the links to The Pirate Bay's pages neither from the Windows Live Messenger, nor through other clients supporting the protocol. However, links to other P2P networks are allowed.[67]

"i'm" initiative[edit]

The i'm initiative was a program Microsoft launched in March 2007, that connects the user with ten organizations dedicated to social causes through Windows Live Messenger, only for conversations sent or received in the USA. Every time someone had a conversation using i'm, Microsoft Corp. shared a portion of the program's advertising revenue with the organization of the user's choice. There was no set cap on the amount donated to each organization. The more i'm conversations the user had, the more money went to one of the ten causes. Each participating organization was guaranteed a minimum donation of $100,000 during the first year of the program. The i'm initiative worked with version 8.1 and above.[citation needed]

In March 2010, the initiative concluded, having raised over 3 million dollars.[68]

Interoperability[edit]

On October 13, 2005, Yahoo! and Microsoft announced plans to add interoperability between their messenger services.[69] The announcement came after years of third-party interoperability success (most notably, PowWow by Tribal Voice,[70][71] Trillian, Pidgin) and criticisms from Tribal Voice and iCast that the major real time communications services were locking their networks.[72] Yahoo! and Windows Live Messenger became interoperable on July 12, 2006.[73][74] For six years, Yahoo! Messenger and Windows Live Messenger users in possession of up-to-date software could communicate across the two networks. Instant messaging as well as transmission of emoticons, nudges, offline messages, presence information and personal status messages were supported.[75] On December 14, 2012, the interoperability ended.[76]

Interoperability with Facebook Chat was added on September 30, 2010, with the launch of Windows Live Messenger 2011.[citation needed]

Platforms[edit]

Messenger Mobile WAP version

Versions were developed for Windows, Xbox 360, Mac OS X (later under the name Microsoft Messenger for Mac), BlackBerry OS, iOS, Java ME, S60 on Symbian OS 9.x, MSN TV, Zune HD,[77] Windows Phone, Windows Mobile and Windows CE.[citation needed]

Messenger Mobile (formerly named Windows Live Messenger Mobile) was the version of Messenger that was aimed to be used on mobile devices over a cellular data plan or Wi-Fi (if supported by the phone). There was also a WAP-compatible version that may be used on any mobile device, and also specific client versions designed for Windows Mobile, iOS, BlackBerry and Nokia Series 60 devices.[citation needed]

Windows Mobile[edit]

A client version of Windows Live Messenger Mobile was a part of client application named "Windows Live for Windows Mobile" included with the Windows Mobile 6 operating system. It was included on both Windows Mobile 6 smartphone edition (non-touch screen phones) and professional (touch screen phones). Among other features you could send voice-clips (max 10 seconds), pictures & emoticons.[citation needed]

Xbox[edit]

Windows Live Messenger support was included in the Xbox 360 spring 2007 dashboard update released on May 9, 2007.[78] It was known as Xbox Live Messenger.[79]

Those using Windows Live Messenger were able to see the Gamertags of friends logged into Xbox Live, including the games that they were playing. Xbox 360 users could chat in-game or while watching a movie. Although only text chat was supported, Microsoft suggested that voice and video chatting may come in a future update.[citation needed] Support for child accounts was added in December 2007.[citation needed]

To coincide with the arrival of the integration of Windows Live Messenger with Xbox Live, Microsoft released a new Xbox 360 keyboard adapter called the Xbox 360 Messenger Kit for easier text input. The keyboard device attaches to the standard Xbox 360 controller through the headphone jack and features a QWERTY-style key layout with 47 backlit keys. However, any USB keyboard is also compatible with the Xbox 360.[citation needed]

Microsoft also announced on June 14, 2010, that users on Xbox LIVE with the controller-free Kinect could have real-time video conversations with Windows Live Messenger contacts. This feature was enabled at launch.[80]

MSN TV (WebTV)[edit]

MSN Messenger on MSN TV 2

Starting in the summer of 2000, the Microsoft-owned web access product MSN TV (then known as WebTV) introduced a software upgrade for users of its internet terminals that added a basic messaging client among other features. The messaging client was designed to work with the Microsoft Messenger service and was simply named MSN Messenger.[81] The client for the original WebTV/MSN TV internet terminals supported basic presence, plain text messages (no graphical emoticons), and buddy lists, with the overall WebTV/MSN TV service hosting services for users to add, remove, or block Messenger contacts and manage their Messenger settings. Windows Live Messenger support was later added to the MSN TV 2, introducing a new UI to fit the rest of the MSN TV 2's interface and support for graphical emotions. It's believed these clients still worked up until the discontinuation of the MSN TV service in September 2013.[citation needed]

Although WebTV was also available in Japan well before the Summer 2000 upgrade was introduced in the US, it does not appear that Japanese WebTV users ever received this Messenger feature.[citation needed]

Mac[edit]

Microsoft Messenger for Mac (previously MSN Messenger for Mac) was the official Mac OS X instant messaging client for use with Microsoft Messenger service, developed by the Macintosh Business Unit, a division of Microsoft. Its feature list was limited in comparison to that of its counterpart Windows Live Messenger; the client lacked a number of features that its Windows counterpart contained.[citation needed]

The versions 3.x and later of Microsoft Messenger for Mac featured new Aqua graphics, whereas version 2.x and below have graphics similar to Windows Messenger 4.0. Versions 5.x used the brushed metal theme.[citation needed]

  • Version 2.5.1, update to version 2.5, which is a mandatory update to version 2.1 that is available for users running Mac OS 9.2.2.
  • Version 3.5 for Mac OS X revisions older than 10.2.8
  • Version 4.0.1 for Mac OS X revisions 10.2.8 and newer
  • Version 5.1.1 for Mac OS X revisions 10.3 and newer
  • Version 6.0.3 for Mac OS X revisions 10.3.9 and newer
  • Version 7.0.0 for Mac OS X 10.4.9 or newer was released on April 29, 2008.
  • Version 7.0.1 for Mac OS X 10.4 or later includes minor bug fixes.
  • Version 7.0.2 for Mac OS X 10.4 or later: improves overall quality and conversations with Microsoft Office Communicator 2007 R2.
  • Version 8.0.0 beta for Mac OS X 10.5 or later, for Intel Macs only: Official Beta released on March, 24, 2010. Adds A/V conferencing between Mac OS X users and Windows Live Messenger 2009 users.
  • Version 8.0.0 for Mac OS X 10.5 or later, for Intel Macs only: Released with Microsoft Office 2011 for Mac in October 2010 and bears a visual similarity to previous Windows counterparts. It features somewhat more stable functional voice and video calls.

With the release of Microsoft Messenger for Mac 7.0, Microsoft has discontinued the client's support for older versions of their Corporate messaging systems (such as Live Communications Server 2005). The latest version to support these older systems is Version 6.0.3, which is still available for download on the Microsoft website.[citation needed]

Webcam and audio support was delayed due to Windows Live Messenger's webcam and audio engine being reworked, which meant that the Mac version had to wait until this was complete in order for both platform releases to function correctly.[citation needed]

iOS[edit]

The Windows Live Messenger for iOS client supported receiving of instant messaging notifications even when the application closed, and allowed Multiple Points of Presence (MPOP) such that a user can be signed into multiple locations at the same time. Photos and albums could also be uploaded from the mobile devices onto Windows Live Photos, based on SkyDrive, and the application allowed simple image editing capabilities and people tagging within the photos. The application also supported the "Messenger social" feed on Windows Live Profile, allowing users to view and comment on the social updates and activities of their contacts on Windows Live, as well as those on Facebook, MySpace and LinkedIn once these social networks had been connected to Windows Live as a "Service".[citation needed]

Java ME[edit]

Nokia Series 40[edit]

The Windows Live Messenger Mobile client came as a Java ME mobile application pre-loaded on devices such as Nokia 7610, Nokia 7510, Nokia 7210, Nokia 6700c, Nokia 6600s, Nokia 6303c, Nokia 6260s, Nokia 5220, Nokia 5130XM, Nokia 3720c, Nokia 3710f, Nokia, 3600s, Nokia 2730c, Nokia 2700c, Nokia 5530, Nokia 6303c and Nokia X3.[citation needed]

Sony Ericsson[edit]

A version of the Windows Live Messenger Mobile client was also pre-loaded on most Sony Ericsson mobile devices as a Java ME application.[82]

Symbian[edit]

Windows Live Messenger running on an S60 Platform device.

A client for Windows Live Messenger was developed by Microsoft for the Symbian S60 Platform commonly used on mobile phones such as Nokia smartphones and released on August 23, 2007, to selected markets. In May 2009, the client was made available on the Ovi Store. This version of Windows Live Messenger included many of the features of the Windows Live Messenger client, including grouped contacts, voice clips (max 10 seconds), image and file sending; as well as features unique to S60 such as tabbed chat windows and integration with contact list and other features of the S60 platform.[83] When the trial expires the cost to users of Messenger for S60 is £1.50/$2.94 for 30 calendar days of use.[84] As of February 2009, Microsoft stopped charging for Windows Live Mobile and the service is now offered for free.[85]
