Teams camera not working
Blocked camera permission is a common cause. First, run the linked webcam test to see whether the camera can provide an image; nothing leaves your device.
Run the test first
Webcam test
What the webcam test checks
The webcam test checks whether a page can access your camera and receive an image from it. It helps separate a camera access problem from a problem that appears only in Teams. It does not test Teams calls or image quality against a numeric standard.
Read the result as a clue about what to do next. If the test reports NotAllowedError, camera access was not allowed. If it reports NotReadableError, access was allowed but the camera could not be read. If neither appears but Teams still has a problem, use the general Teams steps listed on this page.
Tell which case you have
Run the webcam test linked on this page and note its result. NotAllowedError points to a permission setting: the system or browser has not allowed camera access. Follow the steps for the operating system or browser you use, and choose the steps for Teams on the web if you use Teams in a browser.
NotReadableError points to a camera that another app may be holding, or that Windows security software may be blocking. Close other apps that may use the camera, then follow the listed Windows antivirus step if it applies. On Windows 11 24H2 and later, the page also lists a Basic camera mode step.
If the test does not show either error, but Teams still cannot use the camera, the general steps are to update Windows or macOS and Teams, then make a test call in Teams. The test result narrows down the next step; it does not by itself identify every possible cause.
Why Teams camera problems happen
A permission can be off at more than one level. Windows or macOS may not allow Teams to use the camera. For Teams in a browser, the browser may not have permission. Windows can also have a separate setting for desktop apps, so allowing one setting may not be enough.
A camera can also be unavailable because another app is using it. The listed Windows steps also cover antivirus software that blocks camera access and a Basic camera mode option for some newer Windows 11 systems. When the test points to no clear access error, the page directs you to update the system and Teams and try a test call.
When to seek repair or replacement
The steps on this page cover permissions, other apps, antivirus blocking, a Windows camera mode, software updates, and a Teams test call. They do not include a repair or warranty step, so they do not provide a point at which to request repair or replacement.
If the camera remains unavailable after the listed steps, the test has not established the cause. Use the device maker's support options to ask what to do next, and check whether your device has repair or warranty support.

Questions
Why is my Teams camera not working?
A common cause is that Windows, macOS, or your browser has not allowed Teams to use the camera. Another app may be using it, or Windows antivirus software may block access. Run the webcam test to see which result fits.
What does NotAllowedError mean in the webcam test?
It means camera access was not allowed. Check the permission steps for your operating system, or the browser permission steps if you use Teams on the web. The test does not say which permission setting is off.
What does NotReadableError mean?
It means the page could not read the camera, even though the result is different from a permission denial. Another app may be using the camera. On Windows, the listed steps also check antivirus blocking and, for Windows 11 24H2 and later, Basic camera mode.
The webcam test works, but Teams still cannot use my camera. What should I do?
The test shows that a page can access the camera, but it does not test Teams calls. Follow the general steps to update your system and Teams, then make a test call in Teams.
Does the webcam test tell me if my camera is good?
It checks whether the page can access the camera and receive an image.
