I am running Office Professional Plus 2021 on Windows 11 (Build 22621).
This issue affects the email list pane in the Outlook desktop app. That is, the list of all emails in whatever folder (inbox, sent, deleted, whatever). As far as I know, this is the only place where the problem occurs. When looking at the list of emails in my inbox, I frequently like to use the arrow up/down keys to scroll through the list. One would expect that when you press the down-arrow key, the selection will move down one entry, every time. Sometimes it does, sometimes it moves down several lines, and sometimes it goes up. Same thing happens with the up-arrow key. It does not matter what the sort order is. I cannot see any logical reason for this erratic behavior, which I believe is a bug.
This is a new installation, and the problem existed from day 1.
Has anyone else seen this? Any way to fix it? Is Microsoft aware of this error? It is quite annoying.
Thanks

Hi @CraigD42 ,
Is there any update on this thread? If the issue has been resolved, please mark the helpful replies as answers, this will make answer searching in the forum easier and be beneficial to other community members as well. Thanks for your understanding.
I have not found anything. Just learning to live with it, assuming that eventually it will get fixed, most likely accidentally. My guess is that this is related to Windows 11. Are you running W11 on all those different computers? Has anyone seen this behavior on a Windows 10 computer?

Windows 11 on everything. And, I've tried everything from safe mode OS, safe mode outlook, disabling add-ins. I also have some Windows 10 machines including a 3 year old Dell. The issue is not happening on those. Yeah...I've had the same hope that it gets resolved in an update. But, I'm three months into this bug and it is really hard to live with. I can't even do a basic up and down arrow in my inbox with no modifier keys to move through different emails in my inbox. It even glitches for that. This really cripples productivity.

Only seems to be Win 11, haven't had this issue on any of my Win 10 machines

In my case, using the secondary NVIDIA GeForce RTX 3070 Ti Laptop GPU is the source of the error.
Set Outlook to use the integrated Intel Iris XE Graphics GPU terminated the annoying behavior of the Outlook.
I'm OK with this "solution".
Anyone find anything new on this? I now have it happening on a Dell XPS and a Lenovo P360 tower. This problem does not occur on my several laptops. I've done multiple OS rebuilds carefully adding software back in to see a potential trigger. Current possible software causing this: Remote PC (iDrive), RealVNC, Logitech stuff (LogiTune), Zoom. I haven't definitively pinpointed any one, but those are suspect.
Interesting that you found some potential triggers. I don't have any of those things on my machine. As far as I can tell, this started out from day 1 as soon as I installed office. I can't swear to that, but I really didn't install anything back then that was suspect other than Windows updates. And it doesn't seem to affect any other apps: not even list boxes in outlook's settings pages. Only the Outlook mail folders are affected.
Same problem with brand new Lenovo X1 Windows 11 Pro 22.H2 22621.1265 high-end, all-updated laptop. No other application except Outlook produces this issue.
I found, use of my EXTERNAL MONITOR somehow connects to the error. If no external monitor attached to the laptop, the phenomenon disappears. If my external monitor attached to the laptop, even if the Outlook is on the laptop’s monitor, the erratic behavior returns.
No difference if the monitor is attached directly or by docking station to the laptop, the error is the same.
Other, Windows 10 laptop with the same monitor does not produce the issue.
Windows 11 system problem, I guess.
In my case, the source of the erratic behavior of the Outlook is the using of the second GPU.
By default, Windows chooses which application is served by which GPU. Instead, I set the system to select the integrated Intel Iris XE Graphics GPU rather than the NVIDIA GeForce RTX 3070 Ti Laptop GPU.
It worked, Outlook's bad behavior disappeared.
I set the system to use the NVIDIA GPU for the Outlook, the error returned.

And you did this how? It's one thing to say what you did, but not everyone knows how to achieve this. I'm sure I can poke around and find it, but an explanation in the answer is always helpful to people who have not ever had to mess with such a setting.
Edit: Ok, I did not find it by poking around in Windows, but this article told me: https://www.intel.com/content/www/us/en/support/articles/000090168/graphics.html
I concur that changing the GPU selection to force Windows to use the integrated Intel GPU does fix the problem (didn't even know such a setting existed). However, it has an almost equally annoying side-effect. When set to use the integrated Intel GPU, the performance is noticeably slow. Specifically, sometimes when I hit the arrow key, there is a noticeable pause before the selection bar actually moves. That pause seems to occur at about the same regularity as the scrolling error. The Intel GPU is slow compared to my NVIDIA card, but it's not that slow.
My computer has two monitors, both plugged into the NVIDIA card. The base system has three additional monitor plugs on the integrated Intel graphics. I plan to physically move one monitor (the one where I put Outlook) over to one of those integrated plugs and see if that has any effect. I suspect that it is inefficient to have an app displayed on GPU B while the Windows display internals are using GPU A. I just need to get the right adapter plug since they are display port, but the NVIDIA is mini display port.
"When set to use the integrated Intel GPU, the performance is noticeably slow."
True, I'm not happy with the workaround either. Fast typing lags in Outlook GUI. Microsoft should fix it, I guess.
Latest Intel video driver update fixes the confused scrolling behavior of Outlook when using on external monitor.
On my laptop a CLEAN(!) update of Intel® Arc™ & Iris® Xe Graphics driver update helped: https://www.intel.com/content/www/us/en/download/726609/intel-arc-iris-xe-graphics-whql-windows.html
Driver version: 31.0.101.4314 (date 2023.04.18.)
So I could restore the original settings of Outlook desktop app to utilize maximum GPU performance.
(How? Follow this instruction: https://www.intel.com/content/www/us/en/support/articles/000090168/graphics.html)
No lagged typing, no jumpy cursor when using Outlook on external monitor.
Interesting. This kind of confirms my suspicion that this is a graphics driver bug - and it only affects Windows 11. In my case it seems like it has to be the NVIDIA driver since I am not using the built-in Intel adapter at all. If this affects both NVIDIA and Intel drivers, then I'd bet this is caused by some subtle thing that Microsoft changed in W11 that requires a corresponding change in the driver. For now, I'm just living with the glitchy scrolling.
I confirm: the latest NVIDIA driver brings the ultimate solution.
NVIDIA driver version 31.0.15.2890, date 3/29/2023
