To import OST to Thunderbird, first, you need to convert the OST file to PST format using Outlook. Then, export the emails from Outlook and move them to Thunderbird manually. However, this method can be slow and may not preserve folder structures properly.

For a faster solution, consider using a third-party tool like MailConverterTools OST to PST Converter. These tools allow direct conversion to MBOX format, which Thunderbird supports, ensuring a quicker and more accurate transfer of your data.
