Open the Windows Camera app first; whether it shows an image determines if the problem is in Teams or Windows.
1. Test whether Windows detects the camera
- Select Start, type Camera, and open the Camera app.
- Check for a live image.
- Also check for:
- A shutter or slider covering the lens.
- A camera key on the keyboard, sometimes used with Fn.
- An external webcam that is disconnected.
Microsoft recommends this test to distinguish a Teams-specific issue from a Windows camera or hardware problem.^1^
2. If the Camera app works
Windows can see the camera, so check Teams:
- Close any application that may be using it, such as Zoom, Skype, OBS, or another browser window. Use Task Manager to end those applications if necessary.
- In Teams, select Settings and more (…) → Settings → Devices.
- Under Camera, select the built-in or connected physical camera rather than a virtual camera.
- Confirm that its preview appears, then leave and rejoin the meeting.
If Teams still lists no camera, check Windows permissions:
- Windows 11: Start → Settings → Privacy & security → Camera
- Windows 10: Start → Settings → Privacy → Camera
Turn on:
- Camera access
- Let apps access your camera
- Let desktop apps access your camera
Teams is a desktop application and requires the desktop-app permission. If a setting is unavailable or greyed out, an administrator must change it.^2^
Close Teams completely and reopen it after changing permissions.
3. If the Camera app also cannot find a camera
Check Windows device detection:
- Right-click Start and open Device Manager.
- Look under:
- Cameras
- Imaging devices
- Sound, video and game controllers
- If the camera is absent, select Action → Scan for hardware changes.
- Restart Windows and test the Camera app again.^1^
For an external webcam, reconnect it directly to another USB port before scanning.
On Windows 11, also run:
Settings → System → Troubleshoot → Other troubleshooters → Camera → Run
4. Driver repair if the camera remains unavailable
In Device Manager, right-click the camera and select Properties → Driver:
- If it stopped working after an update, select Roll Back Driver when available.
- Otherwise, select Uninstall Device, then Action → Scan for hardware changes and restart the computer.
- Also check Settings → Windows Update → Advanced options → Optional updates for a camera driver.^1^
Uninstalling or changing drivers may require administrator permission on a work-managed computer. If the camera is absent from Device Manager even after scanning, contact the computer manufacturer or your organization’s IT administrator because Windows itself is not detecting the hardware.
