Guest access to Teams with MFA produces CAA60007 JSON error
Our tenant requires MFA, even for Guests invited to Teams and Azure.
The guest registers and approves the sign-in on the phone, and then gets a question if I want "my organization to manage my device".
If the user click anything except "No, I only want to login to this app", there is an error message thrown back saying there was a JSON syntax error with error code CAA60007. This error should be better managed in the B2B API.
Same here :(
Same here, we use DUO for 2FA, works like a charm, and logging in as a guest at a 2nd tenant, everything works, including receiving this JSON error.

I am seeing the same error. From my point of view, it seems to be a "bug" in the B2B API. I cannot see any reason why a guest should be prompted to allow the other tenant to manage his device.

Got exactly the same case today. But is it really how Teams is designed to behave? I'd rather think it's a technical issue on the guest user's end.
