This article explains how you can grant Full Mailbox rights (to an administrator) when running Exchange 2003 / SBS 2003
Doing the same is easier when running SBS 2008; we’ll do an article on that later.
If, for whatever reasons you might have, you need Full Mailbox rights to a user mailbox when running Exchange 2003 you might be out of luck if you’re using the Administrator account. By default, these rights are explicitly denied by group policies / Exchange policies.
If you don’t feel like doing lots of work, there’s an easy fix to get access to the mailbox: Create an account that isn’t the domain administrator (Or assign the rights to any other user).
- Create a new user or simply select an existing user.
- If you chose to create a new user, make sure to create a mailbox for him – just to be safe. It’s possible that this works without creating one, though.
- Open Active Directory: Computers & Users, and then select the user you want to give Full Mailbox rights.
- Right-click, and choose ‘Settings’.
- On the Exchange Advanced tab, click the ‘Mailbox Rights’ button.
- Click ‘Add’, and select the user.
- Check all check boxes, except the last one. (If you check the ‘deny’ boxes as well after reading this, maybe you admin rights should be stripped forever 😉 )
- Click Ok.
- You can now log into the mailbox by going to http://urltointernalsite/exchange/<<username>> and entering YOUR username and password instead of the ones of the user.
And voilà! You can now read everyone’s private mails do whatever it was you wanted to do.
