Ok, how about this one:
we have a number of groups of users, for example: Service Desk or Service Management, who are using a "resource mailbox". When we create the mailbox we add modify permissons(via AD) to the requestor (for the system managers this is what we call the "owner" of the mailbox). Then the (so called) owner can modify permissions via Outlook to grant rights to other users. All that users add the mailbox via advanced settings to the Outlook view, so all of them see when new messages arrive in the mailbox. When they send messages, it's going to be the "send on behalf of" way. But what if those users need to use the "send as" way? Do I (as Administrator) have to grant them "send as" permissions? And what if those users use their "send as" permissions to send mails as the CEO of the company? Or do I miss something here? Is something, someone, some... prohibiting them from doing this?
