Author: Kelly Last Modified: 2025-04-14

As we know, in Outlook the number beside folder name in Navigation Pane indicates how many unread items are there in the folder as right screenshot shown. However, the number does not include the numbers of unread items in subfolders. Sometimes you just need to know the total number of unread items including subfolders, and how? Try below method:
