Hi

I have seen some people in the forums at http://community.office365.com/ that didn’t realized that enabling Public IM Connectivity (PIC) in Office 365 will actually move the pic federation domain from pointing at the Live Server and being used in Live Messenger to pointing to Office 365 and being used in Lync Online.

So lets say you have your own domain in Live Messenger i.e. tommy@mydomain.com

I now enable my Office 365 beta and add mydomain.com to in the Office 365 management portal. I then click around and enable pic for that domain. BOOM!!

From that moment the move process will start and your live messenger users will not be able to log in with their user@mydomain.com to Live Messenger anymore.

This is actually kind of the same thing that happens when you enable PIC for your on premises Lync server, except that this is a bit easier.

And remember, its still in beta, even though its now a public beta. So don’t play around with your real domain names to much. And read the warnings.
