How to dedupe contacts in Outlook?

What’s the easiest way to get rid of duplicate contacts in Outlook 2007?

Resolve or delete duplicate contacts

"If you save a contact with the same name or e-mail name as one that already exists in your Contacts folder, Microsoft Outlook displays a dialog box with options to either add the duplicate contact as a new contact or update the existing contact with the new information from the duplicate contact. The same choices are offered for resolving duplicate Electronic Business Card.

Another situation in which duplicate contacts are created is when you import contacts into Outlook. In this case, you can delete the unwanted duplicates. You can also turn off the Duplicate Detection feature if you are saving many contacts at one time and want to speed up the process."

It’s a pain. The only way I know how to do it is go through manually and remove the duplicates, at least for Outlook 2007. Not so sure about Outlook 2010. Here is a guide from Microsoft, but essentially, you have to go through your contacts folder and select each duplicate individually, then you can batch delete. Have fun!
