Microsoft Graph Teams Attendance Report for past occurrence

Hi @Keith Thomas ,

There are two ways to get meeting Id of a online meeting if you have joinWebUrl or videoTeleconferenceId as per this documentation:

 -GET /users/{userId}/onlineMeetings?$filter=JoinWebUrl%20eq%20'{joinWebUrl}'  
      
 -GET /communications/onlineMeetings/?$filter=VideoTeleconferenceId%20eq%20'{videoTeleconferenceId}'  

If you know these properties you can fetch the meeting Id (Please refer below example reference)

Example reference 1: Used joinWebUrl property to fetch meeting Id of an Online meeting in Graph Explorer (refer below screenshot)

As per my testing I am able to fetch all the attendance reports for an online meeting using the meeting Id from above response.

Example reference 2: used this Graph API Endpoint GET /users/{userId}/onlineMeetings/{meetingId}/attendanceReports to fetch attendance reports for different occurences for the same meeting (refer below screenshot)

Please cross verify your joinWebUrl as meeting Id for all the occurrences will be same.
