Additional team and channel-related features and issues within Microsoft Teams for Education
Hi Mary_D_434
Thanks for your post in the community.
Based on your requirement, if you use Windows currently, first you need to check Privacy settings in Windows which allow apps to access your camera. (Settings in Windows>Privacy>Camera). Meanwhile, kindly verify the camera is available at other devices/apps.
In addition, please check if the camera is selected in Teams client (Click on the avatar at the right-upper of Teams client>Settings>Devices)
Furthermore, if the issue persists, please sign in Teams web app to check if the camera is available. It is useful to judge if the issue associated to Teams client or your account. Besides, to provide further assistance, kindly share the screenshot about the phenomenon to us.
Looking forward to your update and we’re always be here for you.
Regards,
Joey
