Run and repair and/or re-install Office. Also, check your accessibility settings.
Outlook desktop has resized and is unusually large
Outlook's desktop display has suddenly increased upon a restart this morning. I'm on a Lenovo T16 running Windows 11 with 365. The zoom in/out slide is still at 10 percent. Nothing in the Outlook view settings or my laptop's accessibility settings has changed. And no changes I try to make seem to reset the view to a smaller view. I tried other answers (running outlook in safe mode, disabling all add ins) but nothing has worked. The outlook.exe / cleanviews did not work either. Finally, I tried another suggestion to change DPI settings. Those instructions said to go to properties by right clicking on the desktop icon and going to the compatability tab. When I do that, there is no compatibility tab.
No other 365 app or anything else in my system is appearing unusually large - just outlook. The screen display is optimized and there is nothing different from the last time I used the computer. Suggestions?
