Expected behaviour when sharing files in a meeting with external users

mikkele  Hello, difficult to grasp this one and to be honest I have only given it a brief reading. The main reason I decided to reply is the ending part with "Note:"

Maybe this will help.

- Anonymous users are external users not being federated or invited as guests.
- Federation is set up with external access in Teams.
- Guest access, also set up in Teams (enabled by default), are external users that has been invited to your organization and consequently having a guest account created in your organization's AAD. Sometimes it's necessary to invite an already federated user, for example. You can see the comparison table below.

This is why you have all the Teams meeting lobby options. You can have anonymous users only end up in the lobby, or both anonymous and federated being stuck in the lobby. While guest users with a guest account in your org. (being considered part of your org). let in directly when choosing "all in my org". A new lobby setting is coming where you can put your "true" guests (with an guest account in AAD) in the lobby as well.
