Hi @Mike Abu-awad ,
Welcome to our forum!
I'm afraid the folder pane on left side cannot be moved to right side. It's by design. What we can change is reading pane, more information: Use and configure the Reading Pane to preview messages.
In addition, i notice that you have your email address included in the screenshot, please remember to hide it.
Hope to help you!
