It’s nice and easy to assign (or restrict) staff to particular categories, but I don’t see a way to assign them to select mailboxes. Do all staff have access to all of the configured mailboxes?
In a large helpdesk that might be pulling from many mailboxes, it would be helpful to have control over who is allowed to use a particular address. All it takes is a slip of the mouse, and you’re sending mail from the wrong address.
