Microsoft Teams Camera Not Working

Verify the camera can stream independently, then check Teams camera selection and the permission layers that apply to Teams desktop or web.

Evidence first

What the independent test changes

If DeviceOK passes

A DeviceOK camera pass makes total camera failure less likely; prioritize Teams selection, web permission or meeting policy.

If DeviceOK fails

If DeviceOK cannot stream the camera, troubleshoot privacy shutter, camera detection, browser/OS permission and connection first.

Safe sequence

Check these in order

  1. 1

    Run DeviceOK Webcam Test.

  2. 2

    Confirm Teams has the intended camera selected.

  3. 3

    For Teams on the web, allow camera access in the browser and Teams app permissions.

  4. 4

    Check whether meeting/admin settings have disabled attendee camera use.

Verify

Retest instead of guessing

After changing one setting, run the independent DeviceOK test again before moving to a more invasive step. This preserves evidence and avoids changing multiple variables at once.
