It opens a .pst or .ost from disk, finds messages that are copies of each other in any folder, and saves the unique ones into a separate PST. The file you loaded is read and left alone. 🔰 How to use it 1. Install the app and click Add File(s) to load one PST or OST archive. Outlook does not have to run. 2. In the folder tree, tick Inbox, Sent Items, Archive and any subfolders that should be compared with each other. 3. Under Deduplication options, decide which fields must agree. Subject, Sender and Body text are ticked at first. Recipients, Date/Time sent and Attachment names make the rule stricter. 4. Set Keep as to First found, Oldest or Newest. That copy stays in each group and the others are dropped. 5. Tick the backup PST if you want the removed messages kept in a second file, and leave the CSV report on. 6. Choose a Destination folder and press Start. A message at the end tells you how many unique emails were written and how many copies were left out. 👍 Why IT and office teams pick it - No edits to the source. Since the program only reads the archive, a wrong rule costs nothing. Change the settings and run again. - Folder boundaries do not hide copies. Outlook's Clean Up looks at one conversation at a time, while this tool can remove duplicate emails that sit in Inbox and Archive at once. - RE: and FW: are ignored on request, so a forwarded copy still matches its first version. - Every run leaves a trail. The CSV lists folder, subject, sender, date and whether each message was kept or removed. - Local processing only. Client mail is never uploaded, which matters for legal, medical and finance offices. - The interface comes in 17 languages. ✅ Who uses it - IT staff cleaning a user's archive after a migration or an import that ran twice. - Office managers whose shared mailbox was set up as both POP and IMAP and now holds every message twice. - Anyone with a slow, oversized personal archive who wants to remove duplicate emails before it reaches the size limit. ❓ FAQ Why am I getting two copies of every email in Outlook? The same account added twice, a server that keeps its own copy in Sent, or a repeated import are the usual reasons. Fixing the cause stops new copies, and this outlook duplicate email remover cleans out the old ones. How do I remove duplicates from a PST file? Load it, tick the folders, keep the default rules and press Start. The clean result lands in the folder you picked. Can I remove duplicate emails using the Outlook Clean Up tool?

A license writes the full clean copy. Windows 10 or 11, works offline. - [View Outlook Duplicate Remover pricing details and edition comparison](https://www.g2.com/products/outlook-duplicate-remover/reviews?section=pricing&secure%5Bexpires_at%5D=2026-10-04+07%3A07%3A49+-0500&secure%5Bsession_id%5D=60e92981-eb82-4885-ba58-cfd30b87b3ac&secure%5Btoken%5D=e02fb57ae7fe05fd0021d9eb4930aca8d271607ef6c7b332eddd00be05ed1a0f&format=llm_user) ## Outlook Duplicate Remover Features **Additional Functionality** - Third-Party Integrations - To-Do List - @mentions - Single Sign On - File Management - Activity Dashboard - Drag & Drop - Alerts/Notifications - Prioritization - Access Controls/Permissions - Screen Sharing - Content Management - Brainstorming - AI Copilot - File Transfer - Calendar Management - Status Tracking - Real-Time Notifications - Version Control - Task Management - Activity Tracking - Real Time Editing - Communication Management - Chat/Messaging - Tagging - Generative AI - Assignment Management - Task Scheduling - Project Management - Collaboration Tools - Workflow Management - Secure Data Storage - File Sharing - Document Storage - Task Progress Tracking - Discussions/Forums - Commenting/Notes - Reporting & Statistics - Contact Management - Video Conferencing - Progress Tracking - Mobile Access - API - Document Management - Customizable Branding **Sorting & Filtering** - Attachment Search - Tags - AI Sorting - Predefined Rules **Integrations** - Microsoft Outlook Integration - Gmail Integration - Apple Calendar Integration - Social Media Integration - Third-Party Integrations **Time Management** - Unified Inbox - Email Automation - Snooze **Generative AI** - AI Text Generation - AI Text-to-Speech - AI Text Summarization - Generative AI **Agentic AI - Email Management** - Autonomous Task Execution - Cross-system Integration **Additional Functionality** - Whitelisting/Blacklisting - Customizable Fields - Signature Management - Shared Inboxes - Email Distribution - Prioritization - Customizable Forms - AI Copilot - Mobile App - Routing - Activity Dashboard - Collaboration Tools - Inbox Management - Queue Management - Drag & Drop - Contact Management - Email Marketing - Data Recovery - Archiving & Retention - Real-Time Monitoring - Autoresponders - Multiple User Accounts - API - Real-Time Analytics - Customer Segmentation - Search/Filter - Support Ticket Management - Canned Responses - Workflow Management - Reporting/Analytics - Chat/Messaging - Response Management - Email Templates - Email Monitoring - Campaign Management - Email Tracking - Access Controls/Permissions - Spam Blocker - Alerts/Notifications - Customizable Templates - Real-Time Reporting - Tagging - Campaign Analytics - Workflow Automation ## Top Outlook Duplicate Remover Alternatives - [Microsoft 365](https://www.g2.com/products/microsoft365/reviews) - 4.6/5.0 (5,549 reviews) - [Front](https://www.g2.com/products/front/reviews) - 4.7/5.0 (2,458 reviews) - [Superhuman Mail](https://www.g2.com/products/superhuman-mail/reviews) - 4.7/5.0 (1,280 reviews)
