Outlook 2016 and Acrobat Pro DC email attachments

I have 1500 emails I need to turn into a PDF. Half of these emails have attachments that are .txt files. I need to create a file with the email and associated txt attachments as one flat PDF. Right now I can create the email PDF and the attachments are attached to the PDF as txt files. I need them to show as a PDF as well so that various parties can print them, in order, without having to try and figure out which attachment goes where.
