Delete a Search Folder
1. In Mail, in the Navigation Pane, right-click the Search Folder.
2. On the shortcut menu, click Delete.
Please Note: When you delete a Search Folder, the e-mail messages shown in it are not deleted, as the items are never stored, only viewed, in a Search Folder. However, opening or selecting one or more e-mail items shown in a Search Folder, and then deleting the e-mail items will delete them from the Microsoft Outlook folder where they are stored.
