1-Click Duplicate Delete for Outlook removes double Outlook e-mails, appointments, notes etc. with a single mouse click. Duplicate contacts aren't simply deleted but merged together so that no information can be lost. Everything can be undone! In 1-click-mode one single mouse click suffices and the duplicates are securely recognized and moved into the wastebasket. No further dialogs or decisions. (IT Pros may of course also use an advanced mode where you can configure and tweak everything. But that's optional.)
