    If you want to open Outlook PST emails in Thunderbird, you need to convert the PST file into MBOX format first because Thunderbird does not support PST files directly. The best way to convert PST to MBOX is by using a PST to MBOX converter that can export emails with all important data like email folders, attachments, sender/receiver information, and formatting.

    The entire process is very simple. Choose the PST file, select MBOX as the output format and click on Start Conversion. Once converted, you can use import options or compatible import tools to import the MBOX file into Thunderbird.

    Tools like TrustVare PST to MBOX Converter can help to smooth this migration process, especially if you are dealing with large PST files or multiple mailboxes. A backup of the original PST file is recommended before doing the conversion so that you do not lose any data during the migration.

    One thing I'd add is that the choice depends on what you want to do after the conversion. If the MBOX files are only for Thunderbird, any converter should work. But if there's a chance you'll move back to Outlook or Microsoft 365 later, make sure the tool preserves the original folder structure and internet headers. Those details become important when replying to old emails or searching archived messages.

    I've used the BitRecover PST to MBOX Converter, and one feature I found useful is that it can split very large MBOX files during conversion. Thunderbird performs much better with smaller mailbox files, and splitting them upfront helps avoid slow indexing and potential mailbox corruption later.

    I'd also recommend importing the converted MBOX into Local Folders first and verifying everything before moving it into your active Thunderbird profile. It's a simple extra step that makes troubleshooting much easier if something doesn't look right.
