In the Microsoft Teams Admin Center there is an option to allow or prevent anonymous users from joining Teams meetings.
In this series of quick tips we continue to spotlight a few easy ways to help you get more productive with Teams. Some of these may be new to you, while others may offer a helpful reminder of options you forgot were there.
To toggle this option On/Off, a Teams administrator or a Microsoft 365 global administrator must do the following:
- Open the Microsoft Teams Admin center
- Click Meetings
- Click Meeting settings
- Toggle Anonymous users can join a meeting
Note: If you allow anonymous users to join a Teams meeting, it is a good idea to configure a meeting policy that forces external users to wait in a lobby before joining the meeting.
See this post for the steps on how to do this.
