How do I mute others in a meeting?

Mute other users in a sound zone with one button.

*This permission is only available to Office Administrators. 

1. In the lower right of your screen, at the top of your participants list, click the red “Mute users in sound zone” button. (As a reminder, a sound zone is an area in Katmai in which only the people in the zone can hear each other.) 
2. Affected users will see a pop-up saying you’ve muted all users in the current sound zone.

This feature applies only to the sound zone you’re in — like an office, meeting room, or coworking space, and will affect everyone in your sound zone except you. You won't see the option to mute all users in hallways.
