Notification for Deleted Non-Series-Master Recurring Events in Microsoft Graph API

Question

I have subscribed to the user's calendar, but when one/few of the recurring events in the calendar are removed, then I only get a notification for the master event of the series along with all the other events that are part of the recurrence.

Is there any way to determine the removed events?

Hello Lucca Toledo,

Thank you for reaching out to Microsoft Support!

Determining which specific occurrences of a recurring event have been deleted using the Microsoft Graph API is not possible. Currently, the API does not send notifications for individual deleted occurrences within a recurring series. Instead, it only notifies you about changes to the series master event.

You can submit this feature request using this support link, which will be monitored by Microsoft team and make the enhancements to Graph API.

Hope this helps.
