Hello,
My infra is exchange2010 SP2ru4 ( 2CSAHUB and 4MBX).
I don't belong to the division and when i schedule a meeting in this roombox with 2 or 3 attendees, I receive the mail that I can't book this roombox (fine for me) but the attendees receive the invitation and can accept it (not fine) because they are not aware that i couldn't book this roombox.
According to you, what is the best method to reach my goal and the last but not the least i can't use a room delegate or room approver.
i am available if you need more precision or some deatils are missing
