I have an old OST file from my Outlook account that I can no longer access because the Exchange server is unavailable. I now want to convert the emails from this OST file into MBOX format so that I can import them into Thunderbird. However, I am concerned about potential data loss, folder structure issues, or email corruption during conversion. Could someone please guide me on the safest and most reliable method to convert OST to MBOX?
