From the developer:
Categorize Plus is a plug-in for Microsoft Outlook. This plug-in enables users to categorize and search Outlook items so that information can be found quickly using the fewest possible keystrokes. This is accomplished by employing drop down menus that contain both categories and subcategories in the form of a selectable menu hierarchy.
