Weird mouse wheel behavior in Outlook and Word (Microsoft 365)

Three years ago, caioclra posted:

https://techcommunity.microsoft.com/t5/word/weird-mouse-wheel-behavior-on-office-2019/m-p/2688039 

I'm running "Microsoft® Outlook® for Microsoft 365 MSO (Version 2308 Build 16.0.16731.20542) 64-bit" (Microsoft 365 Apps for Enterprise, Enterprise semi-annual channel). This has happened for quite some time - it's not new.

 

I see the same thing. In Outlook and in Word, but not in Excel, my mouse scroll wheel (a Logitech M325) will cause document/email body text - _only_ document/email body text, _not_ Outlook's message list - to scroll one extra line most times just after finishing the scroll action that I actually commanded. It almost looks like some too-big-for-his/her-britches software engineer's idea of "cool semi-smooth scrolling".

 

What it results in is (almost every time) unnecessary delay, and (frequently) the viewpoint ending up NOT where I want it/ NOT where my eyes expect it to end up after my brain processes how far and fast I scrolled the mouse wheel and what my eyes saw it doing .. up until right after the end-nope-not-quite-the-end of the scroll operation.

 

Video capture attached - look carefully, three or four times, right at the end of a scroll action, there's a very slightly delayed one-more-line scroll. That's what I want to get rid of.

 

How do I set Outlook (message body) and Word (document body) scrolling in Office (Microsoft 365 Apps for Enterprise) to NOT do this very wrong, one extra line at the end, semi-smooth scrolling, but just to scroll only and exactly as much as my mouse wheel moved?

 

thank you.

    Select “Automatically search for drivers”
    Adjust scroll wheel settings
    Open Mouse Settings (Win + I > Devices > Mouse)
    Adjust “Lines per scroll” (recommended setting is 3-5)
    Turn off “Smooth scrolling” (supported by some mouse drivers)
