1. Manual Deletion – Sort emails by subject, sender, or date, and delete duplicate emails manually.
2. Using Outlook’s Built-in Cleanup Tool – Navigate to File > Options > Mail and use the "Clean Up" feature to remove redundant messages.
3. Creating Rules to Prevent Duplicates – Set up Outlook rules to filter incoming emails and avoid duplication.
4. Using a Third-Party Tool – A specialized tool like Duplicate Email Remover can quickly scan and remove duplicate emails from your PST file, saving time and effort.
5. Export & Re-import Emails – Export your mailbox to a PST file, enable the "Do not import duplicates" option during re-import, and remove repeated items.
