			It uses TWN even on MSNP16, so it gets the ABCH token from the DALogin value from the PassportURLs header. It's currently unknown how it gets the token itself, more information would be appreciated.

From my testing, all the versions I tested (6.0.3, 7.0.2, 8.0.1) use TLSv1 to connect to the login servers, HOWEVER it just uses an old record layer.
More information about this would be very appreciated.

[[File:MSNP_Mac_TLSv1.png]]

* 6.x, 7.x: MSNP14, MSNP13
* 8.x (including beta): MSNP16, MSNP15, MSNP14, MSNP13

This is the only official Microsoft client that uses the TWN auth method after MSNP15 (SSO/RPS was introduced in MSNP15).

== Logging ==

You can enable connection logging on M:M 7 and 8 by enabling it in Preferences (Cmd+.). The file location will be ~/Documents/Microsoft Messenger.log on M:M 7 and ~/Library/Logs/Microsoft Messenger.log on M:M 8.

== Changing servers ==

To change the servers, you'll have to edit the binary data itself using an hex editor.

There's a configuration file (plist) located in ~/Library/Preferences/Microsoft/com.microsoft.Messenger.plist(6.x, 7.x) and ~/Library/Preferences/com.microsoft.Messenger.plist(8.x) that caches some server values (ABCH Server, NS Server, Gateway Server) that should also be changed if the app has been opened before.
