Microsoft has EOL's their MSN protocol. Jitsi is no longer able to connect
to the MSN chat servers.
However, the MSN chat service lives on, speaking the XMPP protocol with a
modified auth protocol, the X-MESSANGER-OAUTH2 SASL mechanism. I have been
able to connect and chat over MSN using XMPP with Xabber.
Examples of other XMPP clients speaking this auth protocol can be found at
It would be awesome if Jitsi would add support for this XMPP auth protocol.
