Hello Dear reader,
Thank you for stopping here!
In the past moths I ahve used Windows Mail (Windows Store app), which had an option to change the background image to any image I browse from my computer.
Now Windows Mail is redirecting me to the new Outlook, anmed Outlook pre version 1.2023.913.400 (Production).
On other froum there is an image of the exact problem:
https://techcommunity.microsoft.com/t5/outlook/no-option-for-background-image-in-outlook-desktop-app/m-p/3811644

Windows Mail left side, Outlook Pre right side.
In settings I can change the Modern Theme (background) to White (Neutral) or Mointains.
Below are Calssical themes which only change the header of Outlook Pre.


I didn't find the image location.
Is there a registry hack to solve this problem or any other way?
I have also tried the normal Outlook (which has no PRE on its icon), but it's customization level of background is more primitive.
I will be glad for any help or advice!
Have a nice day/evening!
