Duplicate Email Remover does exactly what the title says: it finds and removes duplicate emails. With its powerful search function, it can search through any email or folder in Outlook.

Once this Outlook add-in finds duplicates, it marks these emails for easy review. You can also set it to move these messages directly to the Deleted Items folder or another folder of your choice. The trial version is limited, but the flexibility in options of the full license makes Duplicate Email Remover a handy tool.
