A reliable free option to convert PST to MBOX is the “Convert PST to MBOX” utility by Outlook Freeware, which creates MBOX files from Outlook PST while keeping the original folder structure intact.​

What free tool to use

Outlook Freeware’s converter is a desktop utility (not an online uploader), so the conversion runs locally on your computer.​
It can export emails into separate MBOX files per Outlook folder and supports maintaining the same folder hierarchy from the PST.​

Why it’s useful

Because MBOX stores email messages only, this type of conversion is mainly meant for migrating or importing mail into clients that support MBOX (like Thunderbird).​
Also note that items like contacts and calendars won’t be saved into MBOX during conversion.
