Delete meeting from calendar without sending cancellation
It's not currently possible to remove or delete a calendar entry from a calendar without sending out a cancellation to the attendees. This would be a nice feature to have

Exchange (the backend of the mail system) needs the notification to be able to remove the item from the calendar.
It would however be nice to be able to specify that the meeting should be removed silently.
You can also investigate a mailflow to remove those Cancellations https://docs.microsoft.com/en-us/exchange/mail-flow/mail-flow?view=exchserver-2019
