Room mailboxes are a well-known part of Exchange Online. With a little planning, it's easy to add automated bookings for room mailboxes. In this example, we create a room mailbox and configure it to allow salespeople to book customer meetings during a conference.
After writing a script to generate statistics for room mailbox usage, some folks pointed out that the Graph APIs returned the names of meeting organizer in event subjects. Why does this happen? It's no fault of the Graph. Instead, it all comes down to calendar processing settings for room mailboxes.
