Converting docx-file with pdf content to pdf

You are right, your solution works, but only partly! I need the linked pdfs within the document, because when sending the pdf according your solution by mail to an other user, the links won't work. Even when I send it seperatly, the recipient needs to store them in same directory naming as I did the links in. So, this is not usable.

The result of the PDF conversion of the docx file with linked pdfs should be fully operatable after sending (the one pdf file) to someone else (I do not like to attach several pdfs...)

For better understanding: You have meeting minutes (iin docx) with some slides to attach (pdf). The slides are inserted as pdf into the docx file and then the docx file is printed to pdf.
