To export PST files to MBOX without duplicates, the SysInfo PST to MBOX Converter Tool is an ideal solution. The software offers a dedicated Remove Duplicate Mail feature that identifies and removes repeated emails during the conversion process. Users can add single or multiple PST files, preview the mailbox data, and select MBOX as the output format. The tool ensures that only unique emails are exported while keeping the original formatting, attachments, and folder hierarchy intact. This makes it a reliable choice for creating clean, organized MBOX files that can be imported into Thunderbird, Apple Mail, or any other MBOX-supported email client.
