Short version:
Meeting organisers and presenters will be able to prevent meeting attendees from turning their camera on to share video during a meeting. Currently meeting organisers and presenters have no control over whether meeting attendees can share video. Rollout begins mid-April and should complete in late April. 

Details:
By default, meeting attendees will be able to turn their camera on or off to share video, which is the current experience.

There are three ways that meeting organisers or presenters may manage the attendees’ camera.

Before a meeting, the meeting organiser can set Enable camera for attendees to Off from the Meeting Options web page. By default this is on, which means that attendees can turn share their video feed. Note that this change does not mean attendees will be forced to share video. 

Meeting option page with a new setting to choose whether attendees can use their camera to share video.

During a meeting, either the organiser or a presenter can reverse that setting so that all attendees can turn their camera on. They can also enable or disable the camera of individual attendees.

Option to disable or enable camera for an individual attendee after a meeting begins by right clicking on that attendee from the meeting stage or roster.

Note: This setting only affects meeting attendees. It does not affect video for presenters or the meeting organiser.

Availability:
Rollout begins mid-April and should complete in late April.
