New outlook not showing total email count in each folder on windows application

Move the mouse cursor on the folder you will see the count mail.

It isn't wholly unusable; it is unnecessarily inconvenient for managing multiple folders at the same time. In old outlook you can customize per folder whether you display total or unread messages at each level.

hovering/right clicking isn't an acceptable solution

I thought about switching to the New Outlook for a second because of a feature that doesn't exist in the Old Outlook, but does in Mobile: Declining an event still shows up in the Calendar as a Declined Event if you decline on Mobile, but not on Old Outlook. Apparently, it also works this way in New Outlook.

So I opened up New Outlook (which I previously dismissed for lacking features I can't remember which) and tried to replicate my Favorites setup and immediately ran into this issue that I couldn't figure out how to find Properties for the option to show the number of emails in a (search) folder...

Pretty annoying that new features are being added to the New Outlook but the older features aren't even there, am I supposed to use both New & Old to access all the features...? Seems like it's been 2 years and New Outlook still hasn't caught up to the Old one's basic features...

Ditto to what's been said already...and...this was a problem with the MAC New Outlook rollout back in October of 2020. It's been solved for MAC users, albeit not satisfactorily: https://answers.microsoft.com/en-us/outlook_com/forum/all/inbox-email-count-in-new-outlook-for-mac/4b1d2cd7-1978-4a6c-9480-bf2706812300
