Although default participant settings are determined by an org's IT admin, a meeting organizer may want to change them for a specific meeting.

You can make changes to your meeting settings before a meeting by going to Meeting options. There are three ways to get there:

1. In Teams, go to Calendar  , select a meeting, and then Meeting options.

2. In a meeting invitation, select Meeting options.

3. During a meeting, select Show participants    in the meeting controls. Then, above the list of participants, choose Manage permissions  .

All of these will take you to a web page, where you'll see a few options for changing participant settings.
