Microsoft Teams - Anonymous Users and Guest Access settings...

[networkmanager]

Morning All,

 

I wonder if someone can help please.

 

Similar to all other schools, we have been experiencing lesson intruders during live lessons in schools within our MAT. Due to this, in addition to enabling the lobby feature, we would like to disable Guest access within our O365 tenancy.

 

Looking within the Teams Admin center, under Org-wide Settings > Guest Access there is an Allow guest access in Teams setting. This is currently set to ON. In addition, under Meetings > Meeting Settings, the Anonymous users can join a meeting setting is also currently set to ON.

 

I understand that if we set the Anonymous users can join a meeting setting to OFF. This will stop external people from being able to join meetings or class teams scheduled within our O365 tenancy. Is this correct?

 

Lastly, does anyone know what the impact of setting the Allow guest access in Teams setting to OFF will be? Do we need to also set this OFF in order to stop the lesson intruders? Just in case, we have existing subject collaboration Teams where some of the members are from schools outside our MAT and O365 tenancy. Will they lose access to these Teams?

 

Thanks.

I have been advised that Guest in the context of this configuration screen means an authenticated guest as appears on the azure active directory users->guest page. It may include Federated users (i.e. other orgs with 365 or GSuite), but that is slightly more unclear to me.

 

That said, I'm not sure any one support group, docs.microsoft.com author, or product team actually understand the full interaction between all thee available settings.

So to clarify: Anonymous:No Guest:Yes is the current recommendation I have received.

Thank you Psydii. I've done some initial testing on this. Setting the Anonymous users can join a meeting to OFF will resolve the issue of intruders joining the classes. However, it will prevent guests from joining any meetings organised from the MAT's tenancy. Will test the impact of the Allow guest access in Teams setting next...
