Some "experts" upgraded us from Exchange 2000 to 2007 six months ago. I notice now that half the 40 users have "Shared Mailboxes", half have "User Mailboxes". From reading a bit, I think they should all be "User Mailboxes".
1. Is that correct, generally?
2. If so, how do I convert them? When I convert them, will users notice? Or is it pretty transparent, etc.
