One of the challenges you may face when converting an office from Microsoft Windows to Linux is that many people archive their e-mail 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 e-mails 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 e-mails already imported the day you switch over.
