Hello,
It seems a general issue, affecting some brands of mouse. My recommendation is to send a feedback to MS Developers using the information in the next article as reference:
As pointed by some members of this community in some cases there is a workaround that restores the scroll functionality:
Workaround 1: Freeze Panels in Excel, then Unfreeze. This should repair the horizontal scroll
Workaround 2: Open first Excel worksheet. Setup freeze panes in it. At this time you can't scroll in either directions. Open a second Excel application instance with a worksheet that has no freeze set. Then you should be able to use themouse to scroll in both directions.
