Using New Outlook on Windows for personal email, calendar, and contact management
The new Outook display is hard on the eyes. Too stark a contrast, whether in dark or light mode, and that leads to eyestrain and frustration. In other words the display is tiring to work with. Classic outlook had a variety of grays, and even the white background was not a brilliant white, which made it a pleasure to read and work with. I suggest you scrap the new look and go back to what worked well for so many years.
