I have a user has been able to access the manager's mailbox, but she doesnt have permissions to access it!! The exchange server is 5.5 and is a member server, the only security lapse I can think of is that the everyone group has full control over the ntfs drive. Any ideas? How ever small your idea it's bound to help!!! thanks in advance..
