Using Classic Outlook on Windows for personal email, calendar, and contact management
Thanks for this
This option is also hidden so users might not see it in Display Setting; it can be found by opening "Settings" and typing "Make Text Size Bigger" and then clicking on the Search result to see this option.
In my case, after an update everything was extremely big and I couldn't focus! I checked everything and couldn't find the issue, I even rolled back the driver. But no luck.
When I checked the Font size it was on the far left, the smallest. But I made the font bigger first and then reverted to small and it fixed the issue.
It seems that you need to remind Windows of the font size.
It's a known Windows issue and MS hasn't fixed it in their patches! disappointing
