I'm trying to use Microsoft Graph Communications API to have a bot join Teams meetings by posting to /communications/calls endpoint. I consistently receive Error 7505: "Request authorization tenant mismatch" even though all configuration appears correct.

I have a web app that joins a teams meeting.

I am sure that i have the same tenant ID in my app and on Azure.

In fact, i have consistently this error message.

The AI told me that i should have Microsoft 365 E5 subscription.

The error is the following:

Error joining bot to meeting: Request authorization tenant mismatch. {"body":"{"code":"7505","message":"Request authorization tenant mismatch.","innerError":{"date":"2025-11-04T16:08:32","request-id":"c2ec15bd-8b6c-4585-94db-696831cce523","client-request-id":"c949e454-3350-771c-d40a-4602653d03d4"}}","code":"7505","date":"2025-11-04T15:08:32.000Z","headers":{},"requestId":"c2ec15bd-8b6c-4585-94db-696831cce523","stack":"Error: Request authorization tenant mismatch.\n

Is that right ?
