I'm developing an add-in for Outlook Web (Outlook365 and Outlook.com) which needs to retrieve all changes in the calendar.
I tried to use the Calendar REST API, but when calling getCallbackTokenAsync
to get the access token, the token I get is scoped, and when I call the Calendar REST API, I get this error:
{"error":{"code":"ErrorAccessDenied","message":"The api you are trying to access does not support item scoped OAuth."}}.
Does anyone have an idea about this or another way to get changed items?
