Converting MS Outlook PST Files To Maildir Format

Falko Timme writes “One of the challenges you may face when converting an office from Microsoft Windows to Linux is that many people archive their emails in PST files. There are PST tools available, but most of them are commercial, since the PST file format is closed and protected by Microsoft. There are several non-commercial methods to achieve roughly the same goal, and in this tutorial we use IMAP (more specifically, courier-imap) to convert all our emails from PST to the Maildir format. The advantage of this approach is that you also lay the foundation for a new mail system, with all your old emails already imported the day you switch over.”
