Teams controls
Teams administrators control organization-wide policies and manage and assign user policies. Teams meeting policies are tied to the organizer of the Teams meeting. Teams meetings also have options to customize specific Teams meetings further.
Teams policies
Teams administrators have the following policies to control the experience for Teams external users in Teams meetings.
| Setting name | Policy scope | Description | Supported |
|---|---|---|---|
| Anonymous users can join a meeting | organization-wide | If disabled, Teams external users can't join Teams meeting | ✔️ |
| Let anonymous people join a meeting | per-organizer | If disabled, Teams external users can't join Teams meeting | ✔️ |
| Let anonymous people start a meeting | per-organizer | If enabled, Teams external users can start a Teams meeting without Teams user | ✔️ |
| Automatically admit people | per-organizer | If set to "Everyone", Teams external users can bypass lobby. Otherwise, Teams external users have to wait in the lobby until an authenticated user admits them. | ✔️ |
| Who can present in meetings | per-user | Controls who in the Teams meeting can share screen | ❌ |
| Blocked anonymous join client types | per-organizer | If property "BlockedAnonymousJoinClientTypes" is set to "Teams" or "Null", the Teams external users via Azure Communication Services can join Teams meeting | ✔️ |
Your custom application should consider user authentication and other security measures to protect Teams meetings. Be mindful of the security implications of enabling anonymous users to join meetings. Use the Teams security guide to configure capabilities available to anonymous users.
