Duplicate Contacts in Outlook
Somehow I duplicated all my contacts in outlook. This happens from time to time, especially if you have a third party link with a smartphone or a practice management software. Microsoft's answer to deleting duplicate contacts is to select each duplicate by holding down the control key and hit delete. When you have 900 duplicates, that is not really a good option.
I found TeamScope's Contact Scrubber for Outlook by using Google and it easily fixed the problem.
The Contacts Scrubber™ for Outlook® provides a means of easily eliminating duplicate records from your 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. You may then merge these items; you can opt to use the program's proposed merge, or override it with your own personal choices, on a field-by-field basis.
