There are multiple tools for Outlook duplicate removal but I can suggest the best tool like Softaken PST Duplicate Remover. The tool quickly scans Outlook files like email, contacts, notes, tasks, calendar, etc, finds duplicate items and removes them within a few clicks. The software has a simple interface for non-technical users and they can easily operate it without any technical skills. It will run on all Windows OS versions like 11, 10, 8.1, 8, and 7 without downloading any other application. It will provide a free trial before buying this tool and after removing duplicate Outlook files it will give a preview and the results
