Search Folders are special folders that can be created within Outlook to gather emails in them from different folders based on specified criteria. The most common criterion is to show unread mail. These folders can be added to Favourites and displayed on top of all folder list.

Important note:  Outlook can display either total number of items next to a folder or number of unread items. The total number of items is displayed in square brackets, the number of unread items is displayed in bold font. To switch between views, right-click a folder in question > properties > General tab.
