Using Classic Outlook on Windows for personal email, calendar, and contact management
From many of the replies my original issue seems to be mis-understood. Yes you can go into any mail folder with the new version of Outlook mail and view unread messages. It is at the top level where you may have several email accounts. On the left is the old Outlook Mail app where it shows the number of unread messages in the INBOX for each mailbox, on the left the new Outlook Mail app where it does not show the count of unread mail messages in the INBOX. I believe many have a problem with this basic feature change.
Thank you for this clarification, I will never switch until this issue is resolved.
