Currently I've been developing a web application that takes advantage of Office 365 Graph API. In my application, it calls the following Update event
in Graph API
https://learn.microsoft.com/en-us/graph/api/event-update?view=graph-rest-1.0&tabs=http
The expected behavior of the API was that each attendee already attending this event should get a notification mail that represents such as "Your calendar event was updated." when the event is updated with the API above. However, the actual behavior was that none of attendees get the notification mail when the event is updated with the API.
I'm wondering if there is a way of getting notification mails for attendees when the calendar event is updated.
FYI: I think if a calendar event organizer manually updates calendar event, attendees can get the notification mail. I would like to realize the same behavior in case of calling Graph API
