Sometimes Outlook will display that there is 1 or more unread emails however when you look in the unread email folder there are none. By following the steps below you can find those emails and mark them as read.
  1. In the “Search Current Mailbox (Ctrl+E)” box, type: read:no and hit Enter.
  2. When it shows “Find More on Server” link, click it. Then the unread email(s) should appear.


This works with Office 2010, Office 2013 and Office 2016.
