Does the New Teams client support disabling of attendee video during a meeting?

Dear raklarr,

Good day! Thank you for posting to Microsoft Community.

To answer your question, Yes, the New Teams client does support disabling of attendee video during a meeting. To disable attendee video during a meeting, the meeting organizer or presenter can click on the ellipsis (three dots) on the meeting control bar and select "Meeting options". In the "Meeting options" window, under "Who can present?", select Specific person or "Only organizers and co-organizers" option instead of everyone to disable attendee video and then click on "Save" to save the change.

If you want prevent mic and camera use before the meeting, after scheduling the meeting and sending out the invite, the meeting organizer can disable the mics and cameras so that attendees can't use them during the meeting. All attendees (but not presenters) will join the meeting with mic and camera off. 

1. Go to Calendar and double-click the meeting.
2. Select Meeting options near the top of the screen.

3. Turn off the Allow mic for attendees? or Allow camera for attendees? toggle and select Save.

However, if you want to prevent mic and camera use during the meeting, kindly click on the "More options" button (three dots) -->Settings -->Meeting Options -->Change "Who can present?" from Everyone to Specific people or "Only organizers and co-organizers" -->Save.

Once you change "Who can present?", the organizer and presenters can disable the mic or camera of all the attendees, or of individuals, at any time during the meeting. To disable all attendee mics or cameras, Select More options   next to Participantsand then Disable mic for attendees or Disable camera for attendees. You can refer to the screenshot below:

For additional information, you can refer to Manage attendee audio and video permissions in Microsoft Teams meetings - Microsoft Support

I hope this helps. If you have other questions or I have got you wrong, please feel free to let me know.

Thank you for your precious time. Have a nice day.

Sincerely,
