Anti-Dupe for Microsoft Outlook is easy to install and easy to use. Using a simple interface, just click on the types of items (email, contacts, calendar, and/or tasks) and choose the folders you want to scan for duplicates within Outlook [1], and Anti-Dupe does the rest. We’ve made the application as simple to use as possible, and while Anti-Dupe does not offer advanced criteria options, you can specify in which folders you would like to delete those annoying Outlook duplicate [1] records.
