Your camera not working in Microsoft Teams is almost always caused by one of three things: Windows privacy settings blocking camera access, the wrong camera device selected in Teams, or a driver issue. This guide fixes all of them.
1. Check You Have Not Turned the Camera Off in the Meeting
Start with the obvious. In an active Teams meeting, the camera icon in the meeting controls at the bottom of the screen shows whether your camera is on. A red slash through it means the camera is turned off — click it to turn it on.
Also check your physical webcam. Many external webcams have a privacy shutter or a physical mute button on the device itself. If the shutter is closed or the light on the camera is off when it should be on, that is your cause.
2. Check Windows Camera Privacy Settings
Windows 11 requires explicit permission for apps to use the camera. If this was reset by an update or a fresh installation, Teams cannot access your camera at all.
- Go to Settings → Privacy & security → Camera
- Ensure Camera access is toggled On
- Ensure Let apps access your camera is toggled On
- Scroll down and confirm Microsoft Teams is toggled On in the app list
If Teams does not appear in the list, it may be listed under desktop apps lower down the page — scroll further and check Let desktop apps access your camera is also on.
3. Select the Correct Camera in Teams
If you have multiple cameras (built-in laptop webcam, external USB webcam, virtual cameras from apps like OBS), Teams may be using the wrong one or one that is not connected.
- Click the three dots (···) next to your profile picture → Settings → Devices
- Under Camera, select your preferred device from the dropdown
- A preview appears below the dropdown — confirm you can see yourself
If the preview is black but the camera is selected, the camera is either in use by another app or has a driver problem (see below).
4. Close Other Apps Using the Camera
Only one app can use a webcam at a time on most systems. If Zoom, OBS, Skype, or another video app is open and has claimed the camera, Teams cannot access it.
- Close all other apps that might be using the camera
- Open Task Manager (Ctrl + Shift + Esc) and end any lingering processes from video apps
- Restart Teams and test the camera
5. Test the Camera in Windows Camera App
This tells you whether the problem is with the camera itself or specific to Teams:
- Search for Camera in the Start menu and open the Camera app
- If your camera works here, the problem is in Teams (go to steps 3, 6, 7)
- If the Camera app also shows a black screen or error, the problem is with the camera driver or device
6. Update or Reinstall the Camera Driver
An outdated or corrupted camera driver causes black screens in Teams and the Camera app.
- Right-click Start → Device Manager
- Expand Cameras
- Right-click your camera → Update driver → Search automatically for drivers
If updating does not help, try uninstalling the driver:
- Right-click the camera in Device Manager → Uninstall device
- Tick Attempt to remove the driver for this device if the option appears
- Restart the PC — Windows reinstalls the driver automatically on restart
For external USB webcams (Logitech, Razer, Jabra), download the manufacturer’s software and driver directly from their website rather than relying on Windows Update.
7. Disable Hardware Acceleration in Teams
GPU hardware acceleration conflicts with some webcam drivers and causes black screens or freezing video:
- In Teams, click the three dots → Settings → General
- Tick Disable GPU hardware acceleration
- Restart Teams
8. Clear the Teams Cache
A corrupted Teams cache can cause camera issues that persist even after the driver is working correctly:
- Fully quit Teams — right-click the system tray icon → Quit
- Press Win + R, type
%appdata%\Microsoft\Teams - Delete the contents of the
CacheandGPUCachefolders - Reopen Teams
Camera Works but Video is Blurry or Laggy
If the camera is detected but the quality is poor during calls:
- Check your internet connection — Teams reduces video quality automatically on slow connections
- Ensure lighting is adequate — webcams perform poorly in low light, which Teams’ background blur enhancement can make worse
- In Teams Settings → Devices, turn off Background effects if you have a blur or virtual background active — these are GPU-intensive and can cause lag on older hardware
- Close other applications to free up CPU and memory during the call
