PST to Thunderbird Converter
Thunderbird is one of the most used email clients in the world. And there are plenty of reasons for that. First of all, it is an open source client, which means that the source code is available for anyone to see and edit, and create plugins and extra functionality for the client. Many advanced computer users love the open-source programs.
But Thunderbird has a huge appeal to many basic users as well. The top reason is that it is free. Most of the commercial email clients come at a cost. But Thunderbird, in spite of its huge functionality and a wider range of features, it can be downloaded for free by anyone.

For them, that are not aware of the email migration terminology, let me give you primer on that:
- Email Migration – as the word itself sounds, it is the task of migrating data from one email client to other. It usually refers to the locally stored data and not on servers.
- Data files – these are the kind of files that an email client uses to store data. Some email clients are supported for various kinds of formats, some are not.
- PST file – PST is a data file that Windows Outlook uses. It’s a proprietary file format by Microsoft. And Windows Outlook cannot backup data in any other format.
- Thunderbird data file – Thunderbird supports several file formats to import/export data, like MBOX, but it cannot yet import PST files from Windows Outlook.
- File Conversion as opposed to IMAP – File conversion method requires conversion of data files directly. IMAP method requires you to upload the data to a server, and then sync it back to the output email client
Let’s come back to the email migration itself now.
