How to mute others

1. Click on their name on the right side of the screen and select Mute Participant (or unmute if they are already muted)

   

2. If a user is muted, they receive a notification letting them know.  They can unmute themselves if they need to be heard.

(NOTE: In any Microsoft Teams Meeting with more than 5 people, any users who join after the meeting has started will join as muted.)
