(Updated) Microsoft Teams: Attend Microsoft webinars from Teams Rooms on Android

🚨 The Signal: Teams Rooms on Android will now support joining webinars and structured meetings as attendees. This enhances meeting participation but requires careful configuration of room device permissions to maintain security posture.

The Impact

Admins managing Teams Rooms devices are affected, with a low security risk if existing meeting policies are not reviewed for room device participation.

• Admins: Must review meeting policies to ensure room devices have appropriate attendee permissions.
• Security Teams: Should verify that room devices cannot inadvertently gain elevated privileges in structured meetings.
• Users: Can now join webinars from MTR-A, potentially exposing sensitive meeting content if rooms are not secured.

The Action

1. Review existing Teams meeting policies in Teams Admin Center (https://admin.teams.microsoft.com) under 'Meetings' > 'Meeting policies'.
2. Verify that policies applied to Teams Rooms on Android devices enforce 'Attendee' roles for structured meetings and webinars.
3. Ensure 'Who can present' settings in meeting policies are configured to 'Only organizers and co-organizers' or 'Specific people' to prevent room devices from presenting inadvertently.
4. Audit Teams Rooms Pro license assignments to ensure only authorized devices are enabled for this functionality.
5. Regularly review device access logs for MTR-A devices to detect any unauthorized role changes during structured meetings.
