Additionally if a calendar update is auto-processed it will be moved to the Deleted Items Automatically. The most common occurrence of this is when the Meeting Comments are updated.
Currently, the messages will NOT be auto-processed:
* if the location is changed
* if the date, time, or recurrence pattern changes
* if the attendee is @mentioned in the meeting body
* if the attendee has not responded to the meeting (accepted or declined)
* if the changes occur within 15 minutes of the meeting start time All other changes to events will be auto-process on the users calendar and the message is moved silently to the deleted items folder.
