Remove default right to 'open other users folders' from Exchange 2003

Posted on 2007-10-15
Last Modified: 2010-03-06
We have an Exchange 2003 Server which appears to have given all users access to all mailboxes via the open other user's folder method i.e. I can go to any users Outlook and give them access to any other inbox in our organisation even though I haven't specifically setup permissions.

    Accepted Solution

    In Exchange System Manager, look for the mailbox store.  On the permissions tab, you may see an entry like Everyone - Read .  Or something like that.  Look for anything that gives your users Read permission across the whole Information Store.

    Have you searched this site? This question comes up frequently. It will be all users membership of a group they shouldn't have access to, or someone has granted them permissions.

    Send As/Receive As and Full Mailbox Permissions are the usual culprits.
