The Exchange Online calendar assistant is good at responding to meeting requests for rooms. It can be even better with just a little customized text to remind those who book the rooms about meeting etiquette. Even though we might never get back to physical meetings in conference rooms, some face to face gathering will happen in the future, so now’s the time to prepare for bookings to be handled in a nicer fashion.
