Backup and restore calendar permissions

[meain]

• Calendars have calendarPermission as a relation and we are not currently backing up that information.

• Beta API has isShared filed which could be used to figure out if the calendar has been shared and decide if we should make another request to get the permissions

• According to docs, we can fetch calendar permissions via GET /users/{id}/calendar/calendarPermissions/{id}, but giving a 500 error when trying to fetch it. The 3rd option to fetch by item id was also giving an error.

  {
    "error": {
        "code": "ErrorInternalServerError",
        "message": "An internal server error occurred. The operation failed."
    }
  }

• We can however get user's primary calendar permission(just the primary cal) via GET https://graph.microsoft.com/:version/users/:user/calendar/calendarPermissions

  • Example available in docs
  • When not shared with anyone, the user calendar has the following

    {
      "@odata.context": "https://graph.microsoft.com/v1.0/$metadata#users('JohannaL%4010rqc2.onmicrosoft.com')/calendar/calendarPermissions",
      "value": [
        {
      "id": "RGVmYXVsdA==",
    	      "isRemovable": false,
          "isInsideOrganization": true,
          "role": "freeBusyRead",
          "allowedRoles": [
            "none",
        "freeBusyRead",
            "limitedRead",
            "read",
            "write"
          ],
          "emailAddress": {
            "name": "My Organization"
          }
        }
      ]
    }
