Organisation et accès aux informations de contact dans Outlook.com
Hello!
Can you confirm if you are using Outlook for Microsoft 365, Outlook 2021, or Outlook on the web?
In Outlook for Microsoft 365 and Outlook 2021, you can bring back the count by right-clicking the folder in Favorites, selecting Properties, then choosing "Show number of unread items" under the General tab. If you are on Outlook on the web, the unread count should display by default and cannot be turned off. Hope that helps!
Regards,
Arlene D.
