Allow external access for Teams meetings but restrict external access using federation for Teams
I would like to allow external access for all users in a tenant to be able to hold Microsoft Teams meetings (we are not using Skype for Business) BUT I would like to restrict external access for use with Microsoft Teams teams and channels to domains that I purposefully allow federated access to in my tenant. I don't want it to be all or nothing where I can only communicate with federated domains and not allow messaging and meetings with domains outside of that list OR I have to allow all domains but block domains I don't want people to add to Teams as external users. We need to be able to separate meeting access from collaboration access.
How to allow whitelisted domain to joined meeting without turn on "Anonymous users can join a meeting" and guest users also.
