Issue with the STATUS property of an event and office 365

Hi.
It seems impossible to change the STATUS of an event from anything to CANCELLED, and from CANCELLED to anything with office 365.
I use davmail v4.8.2 with thunderbird 52.5.0, lightning 5.4.5 and office 365.
I refined the issue.
It is possible to cancel an occurence of a repeating event but it is impossible to cancel all the occurences of a repeating event.
It is also impossible to cancel a one-time event.
It may be a normal behaviour with office 365. I don't have enough knowledge of it to guarantee that this behaviour is the one wanted.

Confirmed: you can't set event status to CANCELLED in Exchange, this status does not exist. However you can delete an occurrence of a repeating event, or delete the event completely. I recently changed delete implementation to send notifications to attendees in this case.
No way to implement a feature that does not exist on Exchange
