Only invited users should be automatically admitted to Teams meetings
Why This Matters
Allowing uninvited participants to bypass the lobby in Teams meetings increases the risk of unauthorized access, data leaks, and potential security incidents such as meeting bombing. By restricting automatic admission to invited users only, you enforce a stronger security posture that aligns with least privilege principles and protects sensitive discussions.
What Aether365 Checks
This check verifies that each Teams meeting policy has the lobby bypass setting configured to allow only invited users. Aether365 flags any policy that permits all users or users from trusted organizations to bypass the lobby, and displays the result in the dashboard under the Teams security checks.
