Dear Sean, I have also taken a photo of the culprit file that keeps remaking itself, everytime I open Outlook. Since Start11 uses two folders to read the start menu items:
Individual:
C:\Users\X1GEN3\AppData\Roaming\Microsoft\Windows\Start Menu
Universal:
C:\ProgramData\Microsoft\Windows\Start Menu
You can see from the photo I just took, that it comes from my Individual folder, AppData....
