We have a user who created a meeting. She heard one of the people invited (let's call him Bob) wasn't coming so she removed Bob from the meeting invitation and sent the update only to Bob. Next thing we know, a meeting cancellation is going out from Bob to the rest of the people originall invited! The meeting is not on Bob's calendar and I can't figure out how an email came from him with "CANCEL: meeting name" in the subject line. Any thoughts? Thanks all.
