Used DbxConv for Windows?
Developer’s Description
By Ulrich Krebs
This program will extract the messages from an Outlook Express (5.0 - 6.0) mailbox and convert it either to the standard mbox or the Outlook Express eml format. The advantage of saving your mail in mbox format is, that it's a plain text format, which can be read by many mail-clients. Converting to eml format is a convenient way to re-import the messages into Outlook Express.
The handling of eml export is a little bit smarter than the one offered by Outlook Express itself. Outlook Express will overwrite messages with same sender and subject, while DbxConv enumerates the messages, so you can be sure none is lost due to conversion.
