I have deleted teams and reinstalled several times. There is no teams int he library/application support/microsoft as is often suggested. I have a background image that is a picture that I took and uploaded. I can add other backgrounds, but when i select NONE it is still the same image. I can work around by having another background, but when i try to adjust greenscreen settting it is screwing withthe background. How can I clear this background image?

    Thanks for the update, Timothy. It’s good to hear the image is gone, but I understand how annoying it is that a solid blue background still shows and the green screen option is greyed out.

    This usually means Teams is still stuck in background mode, even though you selected “None.” It can happen if the app didn’t fully reset its video settings.

    Start by signing out of Teams completely, then sign back in. Sometimes this refreshes your profile settings. While in a video call, click the three dots (...) and go to Background Effects. Even if “None” looks selected, click it again and hit Apply to force it to reset.

    Next, try using the web version of Teams at teams.microsoft.com. Join a test call and see if the blue background appears there. If it doesn’t, that means the desktop app is holding on to some leftover settings.

    Also, check your Mac’s camera permissions. Go to System Settings > Privacy & Security > Camera and make sure Teams has access. If not, some video features may not work properly, including green screen.

    Regards,

    Hey there!

    Nice to meet you! I'm Randy, an Independent Advisor.

    Hi Timothy, when Teams shows a background even after choosing "None." This usually means the image is stuck in Teams’ cache.

    First, fully quit Teams (right-click the icon > Quit) and make sure it’s not running in Activity Monitor.

    Then, open Finder and press Cmd + Shift + G, and go to: ~/Library/Application Support/Microsoft/Teams/Backgrounds/Uploads Delete any image you see there—that’s likely the one still showing.

    Next, clear leftover data. Check these folders and delete them if they exist:

    ~/Library/Application Support/Microsoft/Teams

    ~/Library/Containers/com.microsoft.teams

    ~/Library/Group Containers/ (look for Teams-related folders)

    Restart your Mac after deleting, and reinstall Teams if needed.

    Best regards,
