How to see 'exception' entries with calendar graph API?

Question

I've tried the list calendar view and events/{event_id}/instances API paths in both the v1.0 and beta API scopes. Neither is returning exception entries for cancelled instances of recurrent events. Any cancelled occurrences seem to just be absent. (Have not checked for 'other changes' exceptions at this point.)

I've seen a few different other questions that reference this with different supposed solutions (such as using the List Calendar View api) or using the beta endpoints, but they don't seem to have any effect.

Is this a known limitation, or is there some other means to query to request these event instances?

Hi @Neulinger, Nathan

According to the Graph API, the isCancelled property of the event property is used to indicate whether the event was cancelled.

Therefore, if you need to search for canceled events, you can filter out all canceled events by adding the $filter query parameter when querying all events.

The query request is as follows:

https://graph.microsoft.com/v1.0/me/events?$filter=isCancelled eq true

You can see the link for specific information, and you can specify the calendar or user to query:

Hope this helps.
