I've never found out yet so all I do is re-open all my saved important emails hightlight the contents and copy and paste in to a word document, around ten to a document, 1 e-mail to a page when possible, and on first page list a table of contents using subject line info or how you want to identify each e-mail. I do this now with all e-mails as they come in and wait until I have enough for loading to CD.
Keep looking in, as I will, someone may come up with a better solution.
