Meeting hosts can mute all participants with one click through desktop or mobile devices. On the desktop, click the "Mute All" button at the top of the "Participants" panel; on the mobile terminal, you need to open the meeting control bar, enter "Participants" and click the three-dot menu to select "Mute All". If someone rejoins the meeting, it may be automatically unmute, but the host can turn off the Allow participants to unmute the option to prevent this. In addition, "Automatic mute when members join" can be turned on in Settings > Meetings > Audio and Video to mute future meetings by default, but this setting is not applicable to temporary calls. It should be noted that only the meeting organizer or co-organizer can perform full mute, the shared screen audio is not affected by mute, and mute will not move members out of the meeting.

If you're hosting a Microsoft Teams meeting and need to mute everyone at once, there are straightforward ways to do it — whether you're on desktop or mobile. Here's how to take control of the audio in your meeting quickly and efficiently.

Mute all participants during a Teams meeting

When you're in a meeting, muting everyone isn't buried too deep. On desktop , while in the meeting, click the Participants icon on the right side of the meeting window. Then, look for the "Mute all" button near the top of the panel. Clicking that will instantly silence all attendees.

On mobile , it's a bit less direct but still manageable. Open the meeting controls, tap Participants , then tap the three-dot menu (?) and select Mute all . This works best when you're dealing with background noise or multiple people talking over each other.

• If someone rejoins after being muted, they might come back with unmuted audio.
• The host can also prevent participants from unmuting themselves by using the "Allow participants to unmute" setting.

How to set muting as default for future meetings

If you often find yourself muting everyone manually, it's worth setting up your preferences so participants join muted by default.

Go to Teams settings > Meetings > Audio & Video . Under the Audio section, toggle on "Mute participants upon entry" . This ensures that whenever you start a new meeting, everyone is automatically muted when they join.

This option doesn't apply retroactively, so if you have an ongoing meeting, you'll still need to mute everyone manually first.

• You can still allow certain people to speak by letting them unmute individually.
• This feature only applies to scheduled meetings, not quick calls or ad hoc chats.

What to keep in mind when muting others

While muting everyone seems simple enough, there are a few things hosts should be aware of:

• Only the meeting organizer or co-organizers can mute all participants.
• Participants who are co-organizers won't be muted unless specifically targeted.
• If someone shares audio via screen sharing, that sound isn't affected by the mute command.

Also, muting someone doesn't kick them out of the meeting — they'll just stay quiet until they unmute themselves (if allowed). So if you're trying to reduce distractions, combining mute settings with camera control can help even more.

That's basically all there is to managing audio for a group in Teams. It's not complicated, but knowing where to click makes a big difference.
