In a Teams meeting, meeting organizers and co-organizers can choose to lock their meetings to prevent subsequent join attempts. Anyone attempting to join a locked meeting from any device will be informed that the meeting is locked.

When a meeting is locked, no one else will be able to join, but invitees can still access the meeting chat, the recording, and other meeting info.

After joining the meeting:

  1. Select Controls  Controls icon in your meeting controls.

  2. Select Lock meeting > Lock.

To unlock the meeting:

  1. Select Controls  Controls icon in your meeting controls.

  2. Select Lock meeting > Unlock.

When a meeting is locked, no additional participants can join, but invitees can still access the meeting chat, recording, and other meeting info.

Note: After participants leave the meeting, they cannot join again until the meeting is unlocked.
