If you want to remove duplicate from Outlook across multiple folders at the same time, start by backing up your PST file. Manual deletion is possible, but Outlook requires you to check each folder separately, which is not ideal for large mailboxes.
To simplify the process, many users rely on software such as SysInfo Outlook Duplicate Remover. After adding the PST file, you can select the option to search for duplicates across folders instead of limiting the scan to a single folder. The tool scans all selected folders together and identifies matching emails based on defined comparison settings. Once duplicates are found, you can choose to delete them permanently, move them to another folder, or create a new PST file without duplicates. This method saves time and keeps your mailbox organized.
