How To Change Background Image of Windows 10 Mail App?

Step 5: Under Personalisation, you will see a Background section. There you will find that default background image for Mail app is selected. You can replace that default image with any other preset image. Or else, if you want to apply a custom image of your choice, then click on Browse button.
