Use Ctrl+Spacebar to unmute

On the Teams desktop app, you can also choose to stay muted to avoid unwanted interruption or noise during a meeting and rapidly respond when called upon. To quickly unmute, hold down the keys Ctrl+Spacebar (Windows) and Option+Spacebar (Mac). Release keys to go back to muted state again.

How to enable:

  1. Go to Settings > Privacy. Make sure Keyboard shortcut to unmute is toggled on.

  2. Join a call or a meeting. Mute yourself.

    1. On Windows, press and hold Ctrl+Spacebar. On Mac, press and hold Option+Spacebar. You'll see an alert regarding temporary unmute. Check to make sure you're unmuted.

    2. When you release the key combination, your mic will be muted again.

Note: Shortcuts in general—including Ctrl+Spacebar and Option+Spacebar to unmute—don't work within the chat box or when apps like PowerPoint Live or Whiteboard are shared in the meeting stage.
