Contacts Scrubber for Outlook provides a means of easily eliminating and merging duplicate Outlook Contacts. It works by processing your Outlook Contacts, looking for possible duplicate items. As it finds duplicates, it presents them to you, displaying field-by-field comparisons of item data, and proposing a logical way of merging the item data into one unique item. The user may then merge these items either by using the program's proposed merge, or overriding it on a field-by-field basis.
