Using New Outlook on Windows for personal email, calendar, and contact management
Same issue here. As a small business, I needed to see if I had email from various sources. Because there was no way to see if I received new email for each account without opening them, I kept missing business because I did not know I had new email in various accounts and I get so busy it can be hard to remember to randomly check them all throughout the day.
I am back to "old" outlook even though it has issues with one of the attorney's calendars, oddly enough, from another Microsoft account.
If they used to be able to show the number of new email next to the email addresses, I am not sure why they cannot just turn that feature back on.
