Hello @Martin Brady
From your message, I understand that your built‑in camera is no longer working and has dropped out during Microsoft Teams calls, and you’re looking to restore it so you can continue using Teams meetings normally.
In most cases, this type of issue is related to camera permissions, Teams device settings, another application using the camera, or a camera driver problem. Sometimes this can happen after an update, restart, or a change in system or security settings.
To better assistance, could you please confirm following information:
- Which operating system are you using (Windows or macOS)?
- Does the camera work in other applications on your device?
- Do you see your camera listed under Microsoft Teams > Settings > Devices, and can you select it there?
- Are you receiving any error messages in Teams when attempting to turn the camera on (such as “camera not detected” or “camera in use”)?
- Did this issue begin after a recent update, restart, or change to your device or security settings?
- Is this device managed by an organization or school (for example, via IT policies or device management)?
In the meantime, please try those steps below:
Step 1: Check camera settings in Microsoft Teams
- Open Microsoft Teams > Go to Settings > Devices
- Under Camera, make sure your built‑in camera is selected
- Use Make a test call to confirm if the camera activates
- Fully quit Teams (right‑click the Teams icon in the system tray and select Quit), then reopen it
Step 2: Check camera permissions on your device
If you’re using Windows:
Go to Settings > Privacy & Security > Camera > Make sure the following are turned On:
- Camera access
- Let apps access your camera
- Let desktop apps access your camera
- Confirm that Microsoft Teams is allowed
If you’re using macOS: Go to System Settings > Privacy & Security > Camera > Ensure Microsoft Teams is checked > Close Teams completely and reopen it after making changes
Step 3: Test the camera outside of Teams
Please check if your camera works in another application, such as:
- Camera app (Windows)
- Photo Booth (macOS)
Step 4: Check for other apps using the camera
Close any other applications that might be using the camera (browsers, recording software)
Restart your device and test Teams again
Step 5: Check Camera Device (Windows only)
Open Device Manager
Expand Cameras or Imaging devices
Ensure the camera is enabled and does not show a warning icon
If needed, right‑click the camera and select Update driver, then restart
If your camera does not work in any application or does not appear in system settings, the issue may be related to the device driver, system configuration, or hardware. In that case, you may need to contact your device manufacturer or IT administrator (if this is a managed school/work device).
