The Background settings page offers a selection of background images. Scroll down to browse through all the built-in images and select one you’d like to try. Click the Preview button and a thumbnail video of you appears with that background. When you find one that works, click the “Apply and turn on video” button.

To change your background to one of the built-in images, click the three-dot menu icon while on a Microsoft Teams video call and choose "Show Background Effects" to open the "Background Settings" panel. Click on an image and then select the "Apply" button. That's all there is to it.

To add a custom background, click on the toggle for the ‘Background settings’ option to turn it on. The ‘Background Settings’ panel will open on the right. Click on the ‘Add New’ button to add a custom background image. On the File Explorer window open that opens, go to the folder where you have custom background images saved and select an image.

Select Chat on the left side of Teams, and click the group chat you’d like to personalize. Above the chat, hover over the profile picture to the left of the group's name to select Change profile picture. A new window will open with the option to upload your own image or choose a pre-set illustration, or an emoji.
