A Microsoft Teams meeting URL will never stop working. However, Microsoft imposes an expiry to CVI coordinates, PSTN dial-in numbers, and other meeting policies or settings, as described in the table below.
Note: For additional information on Microsoft Teams meeting expiration, see https://docs.microsoft.com/en-us/microsoftteams/limits-specifications-teams#meeting-expiration
If you are using a meeting URL that comes from an expired meeting, the RC-Reports call termination will report Meeting not found.
The Teams meeting details will also not give any indication of the expiration. However, when you view the meeting details from an active Teams meeting (from a client that joined via the meeting URL) you can see the coordinates have expired by comparing the audio dial-in information.
There will be two sets (audio dial-in information) in the call.
- One from the original invite, seen in the Outlook invite (which are also expired)
- The second set that work (see the graphic below):
