Assume the following:
- In Office365 a room resource has been created with the default settings.
- A meeting is booked at this room.
- The meeting has started.
The organizer then changes the end-time of the meeting (either to extend it or end it early).
The room auto-replies with
Your meeting request was declined. The invitation was declined because it occurred in the past.
Interestingly, at this point, the event then completely disappears from the room's calendar - as if it never existed.
This is a reasonable use-case. Which settings would allow the organizer to achieve the above scenario without being declined?
