How to Delete Duplicate Contacts in Outlook
Duplicates happen. Sometimes it's the result of funky synchronization software, and sometimes, well... Outlook is a Microsoft product, after all. (Ooooh, cheap shot.) If you've noticed more than a few dupes in your address book, there's a fairly quick and effective way to clear them out. Just follow the illustrated instructions at Tech-Recipes. Interestingly, this 11-step procedure is quite different from the one described in Microsoft's own Knowledge Base (which, for the record, I've used successfully). But the end result should be the same: A squeaky-clean contact list. [via Lifehacker]
