In my company, I got a new notebook with Microsoft Windows 10. It comes with natural scrolling support on the touchpad: Sliding up with two fingers moves the document up. So far, so nice.
Sadly, if I connect a mouse, there is no such option for the mouse wheel: Moving the mouse wheel up, moves the document down. This is rather confusing when switching between touchpad and mouse. Fortunally, I found the tool X-Mouse-Button-Control which can address this behaviour without admin priviliges.
Now all applications have natural scrolling with mouse button, almost all have natual scrolling with touchpad, but for some strange reason, the touchpad scrolling direction for Microsoft Office365 is changed by the mouse scrollwheel setting of X-Mouse-Button-Control. All other applications I tried are not influenced (as supposed!).
Seems like Microsoft themselves did not follow their own Windows programming guidelines, while everybody else did?! How can I switch off this nonsense behaviour?
