If your camera isn't working in Microsoft Teams, first check if it's blocked or disabled by ensuring camera permissions are on and Teams is allowed access on Windows via Settings > Privacy > Camera, and on Mac via System Settings > Privacy & Security > Camera, also checking for any physical camera switches. Second, confirm the correct camera is selected in Teams under Settings > Devices > Camera dropdown menu, especially if multiple cameras are connected. Third, update or reinstall the camera driver through Device Manager on Windows or check for system updates on Mac, while testing the camera in other apps to isolate the issue. Restarting your computer can resolve glitches, and checking with IT admin or contacting Microsoft support may be necessary if all else fails.

If you're trying to join a Teams meeting and your camera isn’t working, it can be frustrating — especially if you’re in a hurry. The good news is, most camera issues in Microsoft Teams are due to simple, fixable problems rather than hardware failure. Let’s go over the most common causes and what you can do about them.

Check if the Camera Is Blocked or Disabled

Teams needs permission to access your camera, and sometimes that permission gets turned off — either by accident or during an update.

• On Windows:
  Go to Settings > Privacy > Camera, and make sure the toggle for "Allow apps to access your camera" is on. Also check that Microsoft Teams is allowed under the list of apps.

• On Mac:
  Open System Settings > Privacy & Security > Camera, and ensure the checkbox next to Microsoft Teams is selected.

  

Also, some laptops have physical camera switches or function keys (like on Lenovo ThinkPads) that disable the camera — so double-check those too.

Make Sure the Right Camera Is Selected

Sometimes Teams might be pulling from the wrong camera — especially if you have multiple cameras connected (like a built-in webcam plus an external one).

To change the camera source:

• In Teams, click your profile picture > Settings > Devices.
• Under the "Camera" section, select the correct device from the dropdown menu.

If you only see one camera but it still doesn’t work, try disconnecting and reconnecting any external cameras or restarting Teams after switching the selection.

Update or Reinstall the Camera Driver

Outdated or corrupted drivers are another common cause of camera issues.

Here’s how to check:

• On Windows:
  Press Win X and choose Device Manager. Expand the Cameras section, right-click your camera, and select Update driver. If that doesn’t help, try uninstalling it and then restart your computer — Windows will often reinstall the driver automatically.

• On Mac:
  macOS usually handles updates through system updates. Go to System Settings > General > Software Update to make sure everything's current.

You can also test your camera in another app (like Zoom or the built-in Camera app) to see if it works there. If it doesn’t, the issue is likely with the camera driver or hardware, not Teams itself.

If none of these steps seem to work, try restarting your computer before digging deeper. Often, a quick reboot can clear up glitches that prevent Teams from recognizing your camera.

It’s also worth checking if your IT admin has restricted camera use (especially on company devices), or reach out to Microsoft support if the problem persists.

But for most people, the above fixes should cover the usual suspects — no need to panic just yet.
