My bot receives 403 "Request authorization tenant mismatch" when joining Teams meeting despite bot and meeting being in the same tenant. All components (app registration, Azure Bot, meeting organizer) are confirmed to be in the same tenant.
Status Code: 403 Microsoft.Graph.Communications.Core.Exceptions.ServiceException: Request authorization tenant mismatch.
Why is the Graph Communications API returning 403 tenant mismatch when all tenant IDs match and all permissions are correctly granted?
