I am Priya Working as a Software Developer on MailConverterTools. If you're looking a robust and reliable solution for the best MBOX to PST conversion, I suggest using the MailConverterTools MBOX Converter Tool. It can export the MBOX folder in various file formats like PST, CSV, MSG, Yahoo, Office 365, Hotmail, and EML files. It can convert both individual MBOX files and entire folders of MBOX files to PST files.
