The two ways to set up Search Folders.
Outlook determines what goes into a Search Folder based on whether a message satisfies certain conditions (for example, if the message hasn't yet been read, it is displayed automatically in the Unread Messages Search Folder). These conditions are the Search Folder's criteria (the characteristics of a message that will qualify it for display in the Search Folder).
After you create a Search Folder, new messages will automatically appear in it if they meet the criteria of the folder — which means that once it has been created, the folder will always keep itself up to date.
As shown in the picture, there are two ways to set up a Search Folder:
On the File
Menu, click New
, and then click Search Folder
In the Navigation Pane
, right-click Search Folders
and click New Search Folder
Either method will open the New Search Folder dialog box, where you have the option to choose from a number of predefined Search Folder options or create a Custom Search Folder.
