Use Search Folders to gather messages marked as Important
By using Search Folders, you can quickly find all messages for which the level of importance is set to Importance: High, irrespective of the folder in which they are located. Messages with the setting Importance: High appear in the message list with the following icon.
Note To find any message or Outlook item quickly, use Instant Search.
To find all messages with the level of importance set to Importance: High, do the following:
In Mail, on the File menu, point to New, and then click Search Folder.
Tip To open the New Search Folder dialog box, press CTRL+SHIFT+P.
Under Select a Search Folder, in the Reading Mail section, select Important mail.
In the Search mail in list, select the mail delivery location that this Search Folder will include, and then click OK.
A new Search Folder called Important Mail is created in the Navigation Pane under Search Folders.
Note Search Folders are specific to a mail delivery location. For example, your delivery location might be your Microsoft Exchange mailbox or a Personal Folders file (.pst) for a POP3 e-mail account. To search multiple delivery locations, you must create a Search Folder for each delivery location.
Tip To make a Search Folder appear in the Favorite Folders pane, right-click the Search Folder, and then click Add to Favorite Folders. You can drag Search Folders up or down in Favorite Folders to arrange them in the order of your preference.
