Editors' Review

Frequent mail merging can result in multiple entries for a single contact in your address book. This simple add-on removes the duplicates--and the headaches they can cause--with just a single click.

1-Click Duplicate Delete for Outlook is an add-on for Microsoft's popular e-mail client. It loads an easy-to-spot button onto the toolbar for the client's interface. This little app performed nicely in our tests. It quickly scanned our contacts and removed multiple entries, prompting us with the results of its search. Removing the duplicates was a snap. The lack of a Help file or explanation for the add-on's functionality was a bit troubling, but the tests ran well, and we didn't seem to lose any contacts we wanted to hang on to.

If you frequently perform mail merges using Outlook, you'll want to take a look at this little tool.
