For a smoother experience, I recommend using the Aryson OST Converter Tool. It’s a reliable and user-friendly utility that directly converts OST files into MBOX format, fully compatible with Thunderbird. You don’t need Outlook installed, and it maintains folder hierarchy, email formatting, attachments, and metadata. Plus, it supports all types of OST files, including corrupted and orphaned ones.
