Hi @GARCIA, DAVID
Do you choose to send notifications to all attendees after you update the meeting?
What does it look like to receive a meeting cancellation notice? If there are screenshots, please be aware of overwriting your personal information.
When you update a meeting, you will receive an email notification like the one below when you send an update to all attendees and may appear in deleted items. This behavior is a design dictate of Outlook.
In general, the meeting time will still be displayed normally in the Outlook calendar. If you don't want attendees to receive confusing meeting notifications, send updates only to attendees who are only added or removed.
