All, I have recently found that one of our user is accessing all mailboxes from his outlook client (outlook XP), we have not changed any of the access permissions since we implmented this, but how can I stop him from accessing any other mail box but his? I have tried to change the mailbox rights through active directory users and computers but I am always coming up on brick walls! Any help appreciated!
