I am in the process of moving over from my dinosaur Exchange 2003 server to Exchange 2010 and one of the things I cam across is the inability to access users mailboxes as I did on 2003. I see that I can grant Full Access to a mailbox and I will be able to then mount it in Outlook, but when I remove it the Mailbox still remains mounted. The only way I have been able to remove it is to remove the ACL Full Access from that mailbox. Is this normal behavior?
Also I need to grant a group Full access to all mailboxes. How can I accomplish that as well.
