Change Windows 10 Mail Background Image Or Make It Blank

To change it, go to Settings > Background Picture and browse to any image on your PC, network, or cloud storage that you want to use. There you go. I guess I just changed the background from fluffy happy clouds to stormy ones…but you get the idea....
