Converting Outlook PST files to PDF (or PDF/A) while including attachments

You can convert your PST files to separate PDF files or combine them in one large PDF file with PDFen. In both cases, the attachments will be included in the PDF. If you convert them directly to PDF/A, you are guaranteed that you can still open the files in 15 years and that they will look the same as they do now.
