Using Classic Outlook on Windows for personal email, calendar, and contact management
It also is possible to set folders to show the total number of items rather than unread items in the old outlook which is how I manage my workflow. See below:
This is effectively a small dashboard that lets me see my outstanding actions across general categories. Hovering over each of the folders to see the number in them takes away any benefit of it being a quick glance status bar. This is something I'd strongly advocate for the return of as it is the sole reason I have not upgraded.
