Is there a simple way to restore mailbox rights to default for mailboxes in Exchange Server 2003? Several of our mailboxes have had the permissions changed to allow someone Send As or Full Mailbox Access for various reasons, but now, we would like to systematically restore the permissions to the defaults as defined in the schema (I would assume it's in the schema). I imagine this can be done with dsacls <ObjectDN> /s, but I don't know where the actual mailbox is located in Active Directory. It makes me nervous that this might break the mailbox is not created yet (no mail sent to it or not accessed by the user), so a any information on that would also be appreciated.
Thanks in advance.
