Oftentimes users accept a meeting request (from an external party) and wish to forward that meeting invitation to their own team AND include a conference room. This requires two steps - using room finder to find an available room, then adding the room mailbox to the forwarded invite.
The "Add Room" button is visible when forwarding internal meetings, but the option is grayed out. There is no "Add Room" button when forwarding an external invite. Is there a way to make the "Add Room" button active in the Forward Message dialog when forwarding all invitations?
