It has been reported that Microsoft will be dropping MSN Messenger in favor of Skype.[1]
From what we’ve been able to gather, it should be possible to use MSN in Adium until March 2014.[2] As of this moment, it is not legally possible for us to integrate Skype support (more information: [3], [4]).
Historically, Microsoft has not necessarily encouraged third-party clients connecting to MSN, but they have been tolerated. Not long ago, Microsoft added an XMPP interface to connect to MSN, however it was lacking features and it will be shut down in October. While it’s possible that they could someday add one for Skype, they haven’t provided any indication of doing so.
We know that many of you rely on MSN and we understand that this news is frustrating. It’s frustrating for us as well because, as of right now, we aren’t left with any options. We’ll have to see how this all transpires over the next year. If we find a solution, you can be sure that we’ll let you know.
