Making a call to {user-id}/calendar/events is returning a 403, even though the specified user has given read access to their calendar.

    Hi @Ryan

    It depends on your context, if your context is a delegated context, then the target user must share the calendar with the logged in user or grant delegated access. See details and an example.

    If your context is an application-only context, then you must grant the Calendars.Read application permission to the calling app and request an access token using the daemon-based client credentials flow.

    Hope this helps.
