Cannot Assigne Full Access Permissions To User's Mailbox Since Moving To Exchange 2010
Posted on 2013-01-24
Hello, I have just recently finished moving all our user mailboxes over to Ex2010 from Ex2007. User mailboxes retained their Full Access permissions from Ex2007. Okay, here is the problem. New mailboxes created on Ex2010 - I cannot assign Full Access permission to some specific security groups we have set up in house. For example, every user mailbox is modified with Full Access Permission for 3 site security groups (Leadership Group, Admin Assistants Group and System Administrators Group). Worked fine on Ex2007. However, on EX2010, these groups do not even appear in the list of users and groups in the
SELECT USER OR GROUP - ENTIRE FOREST.
When I search for the group name, it cannot be found????
Really need to have these permissions set, but no idea what the issue is. Please advise. Thanks.
