I can't remove the blue background in Teams. I can choose different backgrounds but, when I select "None", it reverts to a blue background.

Thank you for posting your question in the Microsoft Q&A forum reaching out regarding the issue with the persistent blue background in Microsoft Teams on your Mac.
When selecting “None” under background effects, Teams should revert to your actual environment without any overlay. If it instead defaults to a blue background, this may be due to a graphics compatibility issue or a residual cached setting.
Here are a few steps you can try to resolve this:
- Restart Teams: Fully quit the app (Cmd + Q) and reopen it to ensure changes are applied.
- Clear Teams Cache: 
- Delete the contents of the Backgrounds folder.
- Restart Teams and try selecting “None” again.
- Check for Updates: Ensure Teams is updated to the latest version via Help > Check for Updates.
- System Compatibility: Some older Mac models may not fully support background removal features due to hardware limitations.
For official guidance on changing or removing backgrounds in Teams, please refer to Microsoft’s support article: Change your background in Microsoft Teams meetings - Microsoft Support
If the issue persists after trying these steps, please let us know your Mac model and Teams version so we can assist further.

That's fantastic news! Thank you so much for following up and sharing the solution with the community.
You are absolutely correct. Newer versions of macOS include system-wide video effects that apply to the camera feed itself, affecting all applications that use it, including Microsoft Teams. It’s an easy detail to overlook, so your discovery is incredibly valuable.
We're glad you're all set, and we appreciate you taking the time to post the resolution. It will undoubtedly help other users who may encounter the same issue in the future.
If any other questions come up, please don't hesitate to reach out.
