Solved

Only people with access to this org can join its meetings

We moved to Teams Only mode two weeks ago and now we have problems with Teams meetings with some organizations. Everything is configured using this checklist: https://docs.microsoft.com/en-us/microso...

Tomas_SI had to ask Premier support and their answer was:
"As you want to communicate with the different organisations who is not a part of your domain that's why we would be require to enable this setting "Anonymous users can join a meeting". And yes this is secure. And if there is the limitation on guest users tenant then those guest wont be able to join so... Because they have restricted there tenant for the same.

And yes for External access there are 3 options which can be set according to the needs of the organization :
Off Completely
On except for blocked Domains: In this you can mentioned the domains which you need to block.
On only for allowed domains: And in this you can mentioned those domains for which you want to communicate "

Thank you for this post/reply. After working for years Guest access stopped and it was only by switching on "Anonymous users can join a meeting" did our Teams meetings start to work again.

I think the terminology is not helping here as a Guest in the context of a meeting is not the same as Guest to the AAD and why this error is popping up.

My interpretation is it is an anonymous user as far as AAD is concerned not as far as the meeting itself is concerned. It would help in the Guest settings to have the function of Anonymous users described as another level such as non AAD registered users can join a meeting or something.

Took hours to found this solution over a week elapsed as well as users finding alternative meeting solutions as the majority of our MS Teams meeting are with external participants.
