To remove duplicate from Outlook inbox, first create a backup of your PST file for safety. Next, open your Inbox and sort messages by subject, sender name, or received date to identify duplicates. You can then manually select and delete repeated emails.
However, if duplicates exist across multiple folders or in large numbers, manual cleanup may not be practical. In that case, using a solution like SysInfo Outlook Duplicate Remover can simplify the process. After adding the PST file, the tool scans the inbox, detects duplicate emails, and gives you options to delete them permanently or move them to another folder. This approach saves time and reduces the risk of accidental deletion.
