Teams doesnt turn on the camera

Hi @Ricardo Cuellar, 

Welcome to Microsoft Q&A forum. 

Thank you for reaching out and sharing your experience regarding Teams functionality. I totally understand how frustrating this is, especially when Teams says “another app is using your camera” even though you are not actively using any other camera app. That message is commonly triggered when something in the background still has a hold on the camera session, or when Windows privacy permissions or the Teams client state prevents Teams from taking control of the device. 

At this point, I recommend trying the troubleshooting steps provided in the Q&A Assist answer, since that guidance is specifically written for the exact symptom you are seeing in Teams.  

Additionally, you can also take these advanced steps to resolve the issue: 

1. Clear Teams cache  

On Windows: 

• Type settings in the search box, and then select the Settings app from the results. 
• Select Apps > Installed apps, and then type Microsoft Teams in the search box. 
• Locate the New Microsoft Teams app from the results, select the More options button (...) on the right, and then select Advanced options. 
• In the Reset section, select Reset. 
• Restart Teams. 

On MacOS: 

• If Teams is still running, right-click the Teams icon in the dock, and then select Quit or press Command (⌘)-Q. 
• In the Finder, open the /Applications/Utilities folder, and then double-click Terminal. 
• Enter the following commands, and press Return after each command: 
  • rm -rf ~/Library/Group Containers/UBF8T346G9.com.microsoft.teams  
  • rm -rf ~/Library/Containers/com.microsoft.teams2  
• Restart Teams. 

2. Check Group Policy or Registry Settings (Advanced) 

Some Windows machines — especially in corporate environments — may have camera access disabled via Group Policy or Registry. 

Group Policy (Windows Pro or Enterprise): 

• Press Win + R > Type gpedit.msc and press Enter. 
• Go to: Computer Configuration > Administrative Templates > Windows Components > Camera 
• Double-click Allow Use of Camera > Set to Enabled. 
• Apply and restart your PC. 

Registry Editor: 

• Press Win + R > Type regedit and press Enter. 
• Navigate to: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\CapabilityAccessManager\ConsentStore\webcam 
• Look for a value named Value or ValueName. 
• Set it to Allow. 

3. Contact IT admin 

If you are using work-issued laptops managed via Intune or Azure AD, camera access may be restricted by your organization. In this situation, only your organization's IT admin can resolve this.  

Moreover, they can also create a support ticket to Microsoft Support on your behalf if the issue requires deeper investigation. 

I hope this information is helpful. Please follow the steps above and let me know if it works for you. If not, we can continue working together to resolve the issue.  

Thank you for your patience and understanding. If you have any questions or need additional assistance, please don’t hesitate to reach out so I can continue to support you. If you found the response useful, please consider marking it as accepted, as this may help other community members who are looking for similar guidance.  

I look forward to continuing the conversation.  

Try these steps to resolve the “another app is using the camera” issue in Teams:

1. Close other apps that might use the camera
   • Quit apps like Skype, Zoom, FaceTime, browser-based meeting tools, or the Windows Camera app.
   • Some may keep running in the background.
2. Use Task Manager to find and stop camera-using apps (Windows)
   • Right-click the taskbar and select Task Manager.
   • Look for apps that could be using the camera and select End task on them.
3. Check Windows camera privacy settings
   • In Windows 11: Start > Settings > Privacy & security > Camera.
   • In Windows 10: Start > Settings > Privacy > Camera.
   • Make sure:
     • Camera access (or Camera access for this device) is turned on.
     • Let apps access your camera / Allow apps to access your camera is turned on.
     • Under the list of apps, ensure Microsoft Teams (if listed as a Microsoft Store app) is turned on.
   • Under Let desktop apps access your camera / Allow desktop apps to access your camera, make sure this is turned on so desktop apps like Teams can use the camera.
4. Test the camera outside Teams
   • Open Start > Camera and confirm the preview works.
   • If the camera fails here too, the issue is with Windows or the device, not Teams.
5. Check antivirus or security software
   • Ensure any antivirus or third‑party security software is not blocking camera access.
6. Restart device and reconnect external camera (if used)
   • If using an external webcam, unplug it, restart the device, and plug it back into a different USB port (preferably a motherboard port instead of a hub/expansion card).
7. Update camera driver (if camera freezes or fails)
   • Start > Device Manager.
   • Expand Cameras.
   • Right-click the camera > Update driver > Search automatically for drivers.

If the camera works in other apps but not in Teams after these steps, focus on step 3 (privacy settings for desktop apps) and step 2 (Task Manager) to ensure no hidden background app is holding the camera.
