Hello @Cristiano Degiorgis,
Based on current research, there is no Graph API available that retrieves a list of deleted occurrences of a recurring event. Since this feature is not present, you may consider submitting a feature request. The Microsoft team will review this for possible inclusion in future Microsoft Graph API updates.
Alternatively, setting up a subscription to track calendar changes through webhooks is possible. This allows you to detect events with change types such as "created," "updated," or "deleted."

You can also use the /delta
API to track event changes. However, it won't provide information on deleted occurrences directly. You can, nevertheless, compare the previous occurrences with the current ones.
Hope this helps.
