If you want to know the total number of email messages in the folder instead, such as for mail folders which store only uncompleted tasks, follow the steps below to change the view to show the number of total messages in the folder:
- In Outlook’s Folder pane, right click on the folder which you wants to show total number of email messages instead of unread messages count.
- Select Properties from the contextual menu shown.
- Select the General tab (if not selected).
- Select Show total number of items.
- Click OK or Apply.
When you change to display total number of messages, the number is shown inside square brackets, i.e. [78], comparing with number in bold without bracket or number in parentheses (depending on Outlook version) for unread email messages count. The behavior allows you to visually identify whether the number reflects the total messages count or the total unread messages count.
In addition, you must repeat steps above for each folder that you want to change as Outlook does not support simultaneous change of multiple folders at the same time.
Note that if you added the folder to Favorites, the setting of total items or unread items apply to what’s displayed in Favorites too.
