Sorry which product does this relate to?

This relates to the Microsoft Graph API. In particular to following issue.
1) I subscribe to receive event resource notifications (https://docs.microsoft.com/en-us/graph/api/resources/webhooks?view=graph-rest-1.0).
2) I create a repeating appointment in Outlook.
3) I remove one of the recurrences.
4) I receive a notification for the series master event that an update occurred.
5) If I call the /instances endpoint (https://docs.microsoft.com/en-us/graph/api/event-list-instances?view=graph-rest-1.0&tabs=http) to see what the update is about, I cannot see that removed event as an exception. Simply it is removed from the response.
So the only solutions seems to be to save all the occurrences on our end and than if an update happens to compare them one by one with the occurrences in the instances response and see which occurrence is deleted if any. Is there a better way than this?

We are on the same page, now we just cancel by comparison with our DB . What I really don't understand is why is there a parameter named 'isCancelled' . Since, whenever someone cancels or deletes an event, it will simply be removed from the response. The logic procedure would be to simply set 'isCancelled' as true, at least for the update hook that this action causes.
- Any updates on this?

I will move your query to the Microsoft Graph community and hopefully someone can help you there.
- Perfect, thank you and sorry for posting it in the wrong place in the first place.
