Hello Winnie,

Are you still a moderator on here? Have you viewed the rest of the comments on this thread? This is not a Surface or Hardware issue. This is an Outlook 2016/O365 issue.

The common connection between all of the complaints, myself included, is that we are experience this on a touch screen device (which scrolls just fine when touching the screen) but is not functional when using the touchpad.

The fact that the little arrows appear at the bottom or top of the calendar, depending on which direction you are scrolling, indicates that this is a programmed "feature" but it doesn't work right, or should have an option to turn in off and allow smooth scrolling. If you "hover" over one of the small black arrows, a hint comes up that says "Click for more appointments". If you click for more appointments it will move down the calendar page, but the time advanced is not consistent (Sometimes it advances an hour, other times less, sometimes it jumps 3 hours).

As the other users have reported, if you use two finger touch and flick the touchpad faster, it will advance scroll or reverse scroll (depending on the direction you gesture) but it goes too far or sometimes not far enough. We want to control the scrolling function and if we don't want to take advantage (although with the current implementation I can't think of ANY ADVANTAGE AT ALL) of gesture speed derived scrolling, then we should have an option in the settings to enforce smooth scrolling in the calendar.

This is a MAJOR ISSUE for many users and will become an even bigger issue with the rapid proliferation of touchscreen devices among professional users.

I am using the latest edition of O365 ProPlus Version 1707 Build 8326.2107

and I'm on a new Dell XPS 15 touch screen laptop that is running Windows 10 Education with all updates.
