This version can now convert both 32 bit Outlook files (pre 2003), and the 64 bit Outlook 2003 pst files. Utilities are supplied to convert email messages to both mbox and MH mailbox formats, and to DII load file format for use with many of the CT Summation products. Contacts can be converted to a simple list, to vcard format, or to ldif format for import to an LDAP server.

The libpff project has some excellent documentation of the pst file format.
