Export Thunderbird to Outlook

To backup Thunderbird emails into PST, there is another better solution people can rely. In this regard, I propose to use Thunderbird Converter Tool. It allows users to convert  Thunderbird mailbox emails into PST and several other file formats like EML, CSV, DOC, PDF, PST, MBOX, HTML, TXT, JSON, and so on. You can check its demo version that converts 50 emails per folder for free.
