Breakout Rooms for Microsoft Teams Webinars now support up to 1,000 participants and 100 rooms

🚨 The Signal: Microsoft Teams webinars now support up to 1,000 participants and 100 breakout rooms. This expands the scale of interactive sessions, potentially increasing data exposure risks in larger, less controlled group discussions.

The Impact

Webinar organizers and participants are affected, with a low security risk related to potential information oversharing in expanded breakout room scenarios.

• Webinar organizers: Increased risk of information oversharing in larger, less supervised breakout rooms.
• Participants: Potential exposure to broader audiences in discussions, increasing privacy concerns.
• Security teams: Need to ensure existing data governance policies adequately cover expanded breakout room usage.

The Action

1. Review and update internal guidance for Microsoft Teams webinar organizers regarding appropriate data sharing in breakout rooms.
2. Communicate to webinar organizers the importance of setting clear expectations for participant conduct and data sensitivity within breakout sessions.
3. Consider implementing sensitivity labels for webinar content if not already in use, to guide data handling.
4. Educate users on responsible information sharing practices within collaborative Teams environments, including breakout rooms.
