Yahoo has rolled out a new feature for its Mail service users to find and merge duplicate contacts in their address book.
To get started, when you first open Yahoo! Contacts, just click the link to “Fix duplicate entries”. (There is also a link in the “Tools” button at the top of your contacts window.)
This tool will scan your contacts list and present you with the duplicate entries that were found. To combine the duplicates into one, just click the button ‘Merge all EXACT’ and then “Yes” to confirm.
You can also review each duplicate contact separately, just click the “Next” button instead. A wizard will guide you through the process of merging each duplicate entry.
