Comment 4 for bug 677739

I don't think so. But today I managed to understand what was wrong in my case.

The MSN server error was due to the fact MSN server can not find my address book associated to my acount. Since it was a very old MSN account which was created with an opensource MSN client (maybe it was Kopete) so I've never log in with that account directly on hotmail web server.

The solution was to log once on hotmail.com web. I think the address book is only created at this time.
