The latest installment of my Hands On Test Drive series features Microsoft Live Messenger 184.108.40.206.3921.717 M2 (beta build). This beta version was released to beta testers last week from Microsoft Connect Program, and I got my copy from a friend. I instantly installed it on my system, but had problems signing in. So I switched back to version 8.5. Well I decided to give it another try today and, thankfully, it worked.
