My Microsoft teams app is not working properly. (I have a windows desktop) When I try to video call through the app it comes up with a message of - Video not working. I have been in touch with the tech support team and they kindly helped me uninstalling and reinstalling the app, hoping to resolve the problem. However, the issue still remains. I have tried accessing it through the browser and the video call works fine - but not through the app. My case number is - 103862787.
Close all other apps that might be using your camera (like Skype or FaceTime).
If you’re using an external camera, try unplugging it and plugging it back in.
You can often save time and effort by restarting your device.
Make a test call:
To make a test call, select your profile picture, then choose Settings > Devices. Then select Make a test call under Audio devices.
In a test call, you'll see how your mic, speaker, and camera are working. Follow the instructions from Test Call Bot and record a short message. The message will play back for you. After that, you'll get a summary of the test call, and you can go to your device settings to make changes.
