Vertical scroll bar keeps jumping to the bottom of the screen

Anonymous

The vertical scroll bar on the far right of my Outlook.com window keeps jumping to the bottom of the screen whenever I click on one of my folders or an email. Then I can't see the ribbon above my emails. I push the scroll bar back to the top, but as soon as I click on a folder again, it jumps back to the bottom of the screen. It happens whether my zoom is at 100% or higher. I tried the repair option and restarting. I contacted Outlook Support and after 40 minutes, they said it's how Outlook is designed and can't be fixed. But it wasn't always this way and just started jumping. I see there was a related issue that was fixed in Feb 2025: https://answers.microsoft.com/en-us/outlook_com/forum/all/issue-with-the-inbox-scrolling-bar/ce34dda6-7f02-4222-8c44-62b2d2ea485d

I am using a laptop. The issue is present in Chrome and Edge.

My current workaround is to use a different mouse, a Logi M240. This is pretty much the bottom of the line for Bluetooth mice, making me suspect there's a race condition somewhere in the morass of code which mucks around with mouse events and it's somehow helpful *not* to have events being rapidly thrown by a high-spec mouse? Well I don't think this defect will be "fixed" by the community but it's now biting me only once in a while (with a right-click menu popping up spuriously, or a left-button drag persisting after I had released the left button). I don't play real-time games so these occasional bites don't have fatal consequences

... although I did have some trouble regaining control of my system after an inaccurate drag-and-drop into a folder caused a few hundred files (totalling more than 10 GB) were plopped onto a OneDrive queue for synching (which soaked up the entirety of my flaky 4G data connection because I hadn't gotten-around to figuring out how to rate-throttle that gluttonous beast)... but I have rate-throttled it now. Always a good idea to close the barn door after the horses have bolted once, as they might do it again! ;-)

Microsoft - when is this issue going to be fixed?????? I have tried all the suggested solutions - no resolution for me.

Microsoft will not figure it out because when it comes to updates its always the community who has to fix the mess, unless the coding is obviously flawed. This happened during an update I believe mid may or mid june.

I believe 3 things may cause it. Mouse drivers, zoom, and display resolution. Maybe even font size or fonts.

So, what I did to fix mine is put font at 12, and resolution to fit more on page or zoom out to fit more. Then the ribbon doesn't disappear. Until this mess is fixed, this might help.

Yes, that works. But then the print is too small.

I was actually able to solve this on my laptop anyway.

In my browser settings I reduced "page zoom" from 100% to 90%. The scroll bar to the far right is no longer there

so no more losing the ribbon when deleting messages or switching between folders.

Down side is the page and font is a little bit smaller.
