Issues with Outlook

@ImteyazAhmad-3342

I understand that you are trying to follow my instructions from the previous version of this question where I suggested that you create a new Question with a Windows tag.
https://learn.microsoft.com/en-us/answers/questions/5922144/in-outlook-if-we-open-multiple-email-the-stack-lis

But the forum moderators have moved this new question back into Outlook anyway. See the note at the end of your original post. Mod moved from Windows Home

I would suggest that you try again, but this time don't mention Outlook or Office. Just say something like "any program that has more than NN windows open and the open windows are stacked on the Taskbar does not show up/down scroll bars". And tag it with Windows for home | Windows 11 | Desktop, Start, and personalization | Task Bar

Please put the link to your new Question in a comment on this thread so I can find and follow it. If they move it back to Outlook or Office again, I'll try to get one of the forum mods to put it back.

Dear ImteyazAhmad-3342,

First of All, Close Outlook and associated windows (Force Close it) Or Restart your Device.

Then,

#UPDATE: If you you using some kind 3rd party tool to modify the UI/Shell/Style of the Windows official UI. Better to revert to the original one and recheck the UI/Outlook again.

Q.: How did you create the new profile?
