Windows Live Messenger (formerly
MSN Messenger) is a
deprecated instant messaging client developed by
Microsoft for
Windows,
Xbox 360,
Blackberry OS,
iOS,
Java ME,
S60 on
Symbian OS 9.x and
Zune HD.
It connected to the
Microsoft Messenger service while also having compatibility with
Yahoo! Messenger and
Facebook Messenger. The client was first released as
MSN Messenger on July 22, 1999 and was marketed under the
MSN branding until 2005 when it was rebranded under
Windows Live
and has since been officially known by its present name, although its
previous name was still used colloquially by most of its users.
In June 2009, Microsoft reported the service attracted over 330 million
active users each month, placing Messenger among the most widely used
instant messaging clients in the world.
Following the acquisition of
Skype Technologies, Microsoft began to promote
Skype and introduced the ability to merge their Skype accounts with a
Microsoft account,
allowing users to communicate with Messenger contacts via Skype, which
had additional features and a wider user base. This led to the
discontinuation of Messenger across the world, excluding
mainland China.
History
MSN Messenger (1999–2005)
MSN Messenger logo, 1999–2006
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. 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.
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. 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, one of the first
VOIP providers.
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.
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,
Windows ME,
NT 4.0, and
Windows 2000, because Microsoft provided a scaled-down new program for
Windows XP, called
Windows Messenger, that it originally intended to replace MSN Messenger with on Windows XP.
That strategy changed when 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. 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.
The next year, 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.
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 is the last version of MSN Messenger that
runs on Windows 98 and Windows Me. This version also introduced digital
ink and handwriting recognition support.
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.
Version 8.0–8.5 (2005–2009)
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.
The first beta of the newly renamed Windows Live Messenger, Beta 1, was released on December 13, 2005.
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.
The second beta of version 8.0, Beta 2, was released on February 26, 2006.
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.
The final beta version, Beta 3, was released on May 2, 2006. 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 U.S., and an option for sounds to be edited and/or turned off.
The official release of Windows Live Messenger version 8.0 was on June 19, 2006.Although no notable changes were made between Beta 3 and the final version,
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.
It included audio and video improvements and fixed up minor bugs.
The first update to Windows Live Messenger was previewed on October 30, 2006, with the release of Beta 1 of version 8.1.
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
A minor update, the Windows Live Messenger 8.1 Beta 1 Refresh, was released on December 13, 2006,
and fixed bugs that were causing some people to be unable to sign in and others unable to see their contact list.
The final version 8.1 was released on January 29, 2007.
No changes were made from the Beta 1 Refresh.
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.
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.
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 will be fully phased in by late October 2009 and began on
September 15, 2009.
The first beta of Windows Live Messenger 8.5, Beta 1, was released on May 31, 2007
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.
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,
a new "bunny" emoticon,
and integration with
Windows Live OneCare Family Safety.
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.
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.
The final release of Windows Live Messenger version 8.5 was released on November 6, 2007, and it introduced no major changes.
Version 14.0–16.4 (2009–2012)
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.
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.
However, these features were not seen in any versions of Windows Live Messenger 2009.
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.
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.
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.
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.
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.
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.
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.
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,
the
Go to my space button, the ability to adjust webcam settings during a video call, the Send button,
some games (depending on your localization) and integration with
Windows Contacts. Other features were replaced, such as
Sharing Folders (replaced by integration with Windows Live SkyDrive) and background sharing (replaced by the "Scene" feature).
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.
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.
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.
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.
On June 14, 2012, Microsoft has 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.
This can be circumvented by running Windows Live Messenger in Windows
XP compatibility mode, thus making it believe it is running on Windows
XP.
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.
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, synchronised 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,
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.
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.
On June 24, 2010, a public beta of Windows Live Messenger Wave 4 was released as part of the new Windows Live Essentials beta
A "beta refresh" of Windows Live Messenger Wave 4 was released on
August 17, 2010 as part of an upgraded Windows Live Essentials beta.
The final version of Windows Live Messenger 2011 (Wave 4) was released on September 30, 2010. On the same date, a version of Windows Live Messenger for
Zune also became available.
On August 7, 2012, Microsoft delivered a new version of the
Windows Essentials 2012 suite, which includes Windows Live Messenger 2012.
Discontinuation
On 6 November 2012, Microsoft announced that Messenger and
Skype services would merge in the first quarter of 2013, with users of Messenger client software moving to Skype.
On 8 January 2013, Microsoft emailed Messenger users and informed them that with the exception of
mainland China, the Messenger service would stop working on 15 March 2013 and users would not be able to sign in.
On 15 February 2013,
ZDNet wrote the
discontinuation email was only sent to one percent of Messenger users, a test group.
On the same day, Microsoft announced its plans to phase out Messenger
in vague terms: What Microsoft calls the "update" process would start on
8 April 2013 with English users and would end on 30 April 2013;
Messenger would remain available in mainland China.
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.
"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.
Features
In addition to its basic functionality and general capability as an
instant messaging client, the latest version of Windows Live Messenger
offers the following features:
Album Viewer
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.
Appear offline to individuals or categories
Windows Live Messenger allow 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.
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.
Social networks integration
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.
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 his or her status is set to
Appear Offline in Windows Live Messenger 2009 or before.
Games and applications
Main article: Games and applications for Windows Live Messenger
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
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. 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 webpages with the user's friends on Windows Live within the web browser
- See links to webpages 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.
Protocol
Windows Live Messenger uses 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."
The protocol is not completely secret; Microsoft disclosed version 2 (MSNP2) to developers in 1999 in an
Internet Draft,
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.
Content filtering
The content of users' messages is filtered on server side of the client. For example, the user can't 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.
"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.
On March 2010, the initiative concluded, having raised over 3 million dollars.
Compatibility
Interoperability
On October 13, 2005,
Yahoo! and Microsoft announced plans to add interoperability between their messenger services. The announcement came after years of third-party interoperability success (most notably,
PowWow by Tribal Voice,
Trillian,
Pidgin) and criticisms from Tribal Voice and
iCast that the major real time communications services were locking their networks. Yahoo! and Windows Live Messenger became interoperable on July 12, 2006.
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.
On December 14, 2012, the interoperability ended.
Interoperability with
Facebook Chat was added on September 30, 2010 with the launch of Windows Live Messenger 2011.
Xbox integration
Windows Live Messenger support was included in the
Xbox 360 spring 2007 dashboard update released on May 9, 2007.
It is known as Xbox Live Messenger
and, less commonly, as Windows Live Messenger 360.
Those using Windows Live Messenger are able to see the
Gamertags of friends logged into
Xbox Live,
including the games 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. Support for child accounts was added in December 2007.
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.
Microsoft also announced on June 14, 2010 that users on Xbox LIVE with the controller-free
Kinect will be able to have real-time video conversations with Windows Live Messenger contacts. This feature was enabled at launch.
Microsoft Messenger for Mac
Microsoft Messenger for Mac (previously
MSN Messenger for Mac) is the official
Mac OS X instant messaging client for use with
Microsoft Messenger service and is developed by the
Macintosh Business Unit, a division of
Microsoft.
However, the feature list is limited in comparison to that of its
counterpart Windows Live Messenger. The client is still maintained and
updated but still lacks a number of features that its Windows
counterpart contains. However, several third-party applications that
have support for the Messenger service, such as
Trillian (software),
Adium and
aMSN, incorporate some of the features missing from the official client.
The versions 3.x and later of Microsoft Messenger for Mac feature new
Aqua graphics, whereas version 2.x and below have graphics similar to
Windows Messenger 4.0. Versions 5.x use the
brushed metal theme.
- Version 2.5.1 is an 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, 24th 2010. Adds A/V conferencing
between Mac OS X users and Windows Live Messenger 2009 users.
- Version 8.0.0 for Mac OSX 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.
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.
