Manage attendee audio permissions in Teams meetings

Do you organize large meetings or present material in them? To avoid random noise and distractions that can quickly disrupt the proceedings, you can mute the mics of all attendees and prevent them from unmuting. Then, when someone "raises their hand" to speak, you can allow them to unmute.

Note: Currently attendees who call in to a meeting using the phone number provided in the meeting details will not be prevented from unmuting.

For information on which meeting participants are classified as "attendees," see Roles in a Teams meeting.

Before the meeting

After scheduling the meeting and sending out the invites, the meeting organizer can turn off the mics so that attendees can't unmute themselves during the meeting. All attendees (but not presenters) will be muted when they join the meeting. 

  1. Go to Calendar and double-click the meeting.

  2. Select Meeting options near the top of the screen.
