If your Outlook mailbox is cluttered with the same emails showing up again and again, this tool can help. The Aryson PST Duplicate Email Remover scans PST files and deletes duplicate items like emails, contacts, or calendar entries. You can choose how to find duplicates, whether by subject, sender, date, or body content. It works with both old ANSI and new Unicode PST formats and does not need Outlook installed. Before removing anything, it creates a backup of your file so your data always stays safe. Moreover, it keeps the folder structure unchanged while cleaning, giving you a clutter-free mailbox.
