[GraphAPI/Office 365 Rest API] please add support for notifications/subscription on Exchange RoomMailBox in delegated API permissions mode
GraphAPI/Office 365 Rest API, please add support for notifications/subscription on Exchange RoomMailBox in delegated mode.
In delegated API permission mode, we are able to get events from RoomMailBox calendar but not subscribe for notifications (webhooks) on events changes
Each time we tried to create notification channel we got :
"message": "Operation: Create; Exception: [Status Code: Forbidden; Reason: Access is denied. Check credentials and try again.]",
Moreover, in Exchange, we have full access on RoomMailBox by using user account we used on delegated mode (user account impersonated). Push notifications channel subscription works with EWS.
If we try it by using Application permission mode, everything is OK.
Could you confirm that you support RoomMailBox (actually it seems you just support UserMailbox & SharedMailBox) calendar events notifications in delegated API permission mode ?
