Camera Not Working in Microsoft Teams? How to Enable It

A camera that works everywhere else but not in Teams is usually a permissions issue, and it’s fixable in a few minutes. Here’s the full troubleshooting path.

Step 1: Check Windows camera permissions for Teams

Windows has a system-level privacy setting that controls which apps can access your camera. If Teams doesn’t have permission, it simply won’t see the camera.

Settings > Privacy & security > Camera

Make sure “Camera access” is toggled on at the top. Then scroll down to “Let apps access your camera” and make sure it’s on. Further down, check “Let desktop apps access your camera” – Teams as a desktop app falls under this category. Make sure it’s enabled.

Step 2: Check Teams’ own camera setting

In a Teams call or meeting, look for the camera icon in the meeting controls. If it has a line through it, click it to enable. This is the in-meeting camera toggle – separate from settings.

Before a meeting, in the pre-meeting screen (“Join now” screen) there’s a camera toggle. Make sure it’s on.

Step 3: Select the correct camera in Teams settings

Teams > Settings (three dots > Settings) > Devices > Camera section

A dropdown shows all detected cameras. If no camera is detected here, Teams isn’t recognizing it. If multiple cameras are listed (built-in + external), make sure the correct one is selected.

Test: there’s a small preview below the dropdown. Your camera feed should appear there if correctly configured.

Step 4: Check if another app is using the camera

Only one application can typically use a webcam at a time on Windows. If Zoom, Skype, OBS, or another app is running and has the camera active, Teams can’t access it simultaneously.

Close all other apps that might be using the camera, then rejoin the Teams call.

Step 5: Update camera driver

Device Manager > Imaging devices > right-click your camera > Update driver. An outdated driver can cause the camera to work in some apps but not Teams, particularly after Windows updates.

Step 6: Reinstall Teams

If nothing above works, a clean Teams reinstall via Settings > Apps often resolves camera issues caused by corrupted app data. Before reinstalling, clear Teams cache: close Teams, navigate to %AppData%\Microsoft\Teams and delete the Cache, blob_storage, databases, and GPUCache folders.

The Windows privacy setting for camera access is the one that blocks Teams silently. Teams doesn’t give you a clear error message saying “camera access denied” – it just shows no camera. Checking Settings > Privacy > Camera takes thirty seconds and fixes it immediately if that’s the cause.

3

another app holding the camera is the one that trips people up in meetings. someone joined a zoom call earlier, didn’t fully close zoom, then jumped into teams and the camera doesn’t work. closing every other app that might touch the camera before a teams call is good meeting hygiene.

4

The Teams device settings preview is underused as a quick check. Before any important call I open Teams settings > Devices and confirm the camera preview is showing. If it’s black there before the meeting, fixing it before joining is much better than troubleshooting mid-call.

5

The cache clearing approach for Teams camera issues works more often than it should have to. Teams accumulates a lot of state in those cache folders and corrupt cache can cause all kinds of issues including camera detection failures. It’s a valid fix even if it’s inelegant.

the “let desktop apps access your camera” toggle being separate from the main camera permission is a detail that Microsoft’s own settings UI doesn’t make obvious. the main toggle can be on while the desktop apps toggle is off, and Teams is a desktop app, so you get no camera access with no clear indication why.
