Outlook has a feature functionality for "Search Folders".
Henrik Walther, at Outlook Exchange, has written a description of how to use this tool:
Using Search Folders in Outlook
Search Folders are a kind of new user interface for the Advanced Find functionality, which has been with us through several Outlook generations. The thing that makes Search Folders new and unique is the possibility for defined search criteria to be saved and represented through a kind of virtual folder in the Outlook client. What this means is it gives us a virtual folder view of the content in one or more "normal" folders, for which a search criteria has been defined.
