When I use Advanced Find to search multiple folders, determining where in the hierarchy each item resides is difficult. The In Folder column shows only the item's parent folder. How can I see the complete folder path?

The only way you can view the full path for an individual item is by using custom code to put that information in a custom field on each item. Outlook 2002 adds a FolderPath property, but it's present only on folders, not on individual items.
