How Microsoft forced its way into a market AOL already owned
MSN Messenger Service went live on July 22, 1999, about two years after AOL Instant Messenger and nearly three years after ICQ. Microsoft was late and priced accordingly: the service was free, and it signed you in with the Hotmail address you already had.
"Communications continues to be the cornerstone of the Internet, and instant messaging is becoming a more prevalent way for people to communicate," said Brad Chase, then a Microsoft vice president, in the company's launch announcement in July 1999.
The shortcut Microsoft chose was interoperability. Version 1.0 let you message AOL Instant Messenger contacts from inside MSN Messenger, using AOL's servers, without an AOL account. AOL read that as theft of its network, changed its protocols and cut Microsoft off. Microsoft found a way back in. AOL blocked it again. The two traded workarounds for weeks before Microsoft gave up and removed the feature, which never returned in any later version.
What AOL could not block was Windows. MSN Messenger did not have to be discovered, downloaded or recommended. It was already on the machine, in a decade when almost every machine ran Windows, and that alone carried it into countries where AOL had no presence at all.
What made MSN Messenger feel different from email
The software rewarded fiddling, which is why people remember it as a place rather than a tool. Your display name was a public text field you could rewrite ten times in an afternoon, and people filled it with song lyrics, private jokes and messages aimed at exactly one person who would know.
Presence was the other half. "Appear Offline" made being unreachable a deliberate act that took one click and needed no explanation, and signing out at night was normal rather than a statement. Read receipts did not exist to argue with.
The feature everyone quotes arrived later than memory suggests. Nudges and winks shipped with MSN Messenger 7.0 in April 2005, alongside Xbox Live integration and handwriting input you scrawled with a mouse. A nudge shook the recipient's whole chat window and buzzed, and it was used almost exclusively to annoy people.
Messenger also sat in the middle of Microsoft's consumer stack. It raised Hotmail alerts, tied into the MSN Spaces blogging service and ran small games such as Minesweeper Flags inside the chat window. For a few years Microsoft had a working social network and treated it as a utility.
Why did Microsoft shut MSN Messenger down?
The name went first. In June 2006, with version 8.0, MSN Messenger became Windows Live Messenger, filing one of the most recognized brands on the internet under a corporate umbrella that meant nothing to the people using it. MSN Messenger 7.5 was the last release to carry the original name.
Usage kept climbing regardless. In June 2009 Microsoft reported more than 330 million active users a month, the highest figure the service ever posted.
Then the ground shifted twice. Facebook added chat in 2008, where the contact list was already built and the switching cost was zero. WhatsApp arrived in 2009 on phones. Messenger was designed for a desk you sat down at and a session you consciously started, and that ritual was disappearing.
Microsoft had bought Skype in 2011 and chose to consolidate on it. On November 6, 2012, Skype division president Tony Bates put it plainly: "We will retire Messenger in all countries worldwide in the first quarter of 2013 (with the exception of mainland China where Messenger will continue to be available)." Messenger still had more than 100 million users at the time. Skype had 280 million, and Skype was the one Microsoft had just paid for.
The migration ran language by language from April 8, 2013 and finished that month. Mainland China, where the service was operated through a local partnership, kept Messenger running until October 31, 2014.
Can you still use MSN Messenger in 2026?
Yes, on a fan server. Escargot is an independent project that reimplements the MSN Messenger and Windows Live Messenger protocols, so the original clients connect to it instead of Microsoft's switched-off servers. It costs nothing, and an account needs an email address and a username.
The classic MSN Messenger releases work, and Windows Live Messenger 2009, version 14.0, is the newest client Escargot supports. Nudges, custom display pictures and the display-name theater all behave the way they did, because the client is the genuine article rather than a lookalike. What you do not get back is your contact list. Everyone you want to talk to has to sign up as well, which is the same problem Messenger solved in 1999 and the reason most people only visit.
Microsoft is not involved and has announced no revival of its own. The MSN name survives as msn.com, a news portal with no messaging product attached to it.
What replaced MSN Messenger, and what replaced that?
Officially Skype replaced it. In practice most Messenger users never arrived. They went to Facebook Messenger, WhatsApp or iMessage, because that is where their friends already were, and Microsoft inherited a shrinking share of a market it had once led outright.
The replacement did not outlast the thing it replaced by much. Microsoft announced on February 28, 2025 that Skype would shut down, and it did on May 5, 2025. "We will be retiring Skype in May 2025 to focus on Microsoft Teams (free)," wrote Jeff Teper, Microsoft's executive vice president for apps and agents, in the announcement. Skype credentials now sign users into Teams, with chats and contacts carried across.
So the line runs MSN Messenger to Windows Live Messenger to Skype to Microsoft Teams, and the only survivor of the four is a work tool with a calendar in it. The thing people actually miss, the 2005 version with the buzzing windows and the song-lyric display names, exists in exactly one place, and Microsoft does not run it.
Frequently Asked Questions
When did MSN Messenger shut down?
MSN Messenger, renamed Windows Live Messenger in 2006, was retired language by language starting on April 8, 2013, after Microsoft announced the decision on November 6, 2012. Mainland China was the one exception and kept the service until October 31, 2014. Every user was pushed to Skype, which Microsoft then shut down itself on May 5, 2025.
How do you get MSN Messenger working again in 2026?
Install an old MSN Messenger or Windows Live Messenger client and point it at Escargot, a free fan-run server that rebuilt the protocol Microsoft switched off in 2013. Escargot supports the classic MSN Messenger versions and Windows Live Messenger 2009, version 14.0, and signing up takes an email address and a username. Microsoft offers no official way to run MSN Messenger in 2026.
Why did Microsoft replace MSN Messenger with Skype?
Microsoft bought Skype in 2011 and decided to run one messaging product instead of two. When the retirement was announced in November 2012, MSN Messenger had more than 100 million users against Skype's 280 million, so Skype won the merge. Most Messenger users moved to Facebook Messenger or WhatsApp rather than Skype, and Microsoft retired Skype in turn on May 5, 2025.
