I recently deleted an exchange user by mistake. This user was the user for an Exchange 2010 Room Mailbox. Now I cannot delete, edit or in anyway manipulate the room box. I would settle for deleting the Room box and starting over or any alternative but I want that room box out of the Rooms list in outlook.
Just about any solution would be fine as long as the Room box is not visible in the Rooms list in Outlook.
Server 2008 r2
also, if it is deleted then surely it should auto-disappear from outlook list
