If you have Adobe Acrobat (one of the paid for Pro versions- not Adobe Acrobat Reader), the Adobe Print option should be added to the print list by default.
If it isn’t, perhaps a Repair Installation might add it for you.
Alternatively, you can try add it manually.

You could add a PDF Print Driver to give you what you want (add *PDF Print) to the print list. An example being CutePDF - http://www.cutepdf.com/Products/CutePDF/writer.asp

If you have the Office 2016 package, it should come with OneNote and using that option from within Outlook 2016 allows you to send an message to OneNote and Export the message in PDF format to a location of your choice.
I have the OneNote icon in the Ribbon by default in the Move section:



When you click the OneNote tab, it will open a dialog box and ask you where you want to save the message – something like this:



I have select Unfiled Notes (Personal) and checked ‘Always send e-mail notes to the selected location' (this can be changed in the options later if it’s not what you want. ‘ > OK.

OneNote will open, with the email message on view.
Click File > Export > Export Current (Page) > Export Format (PDF) > Export.



You should get box opening for a save location. PDF is already used as File Type. Just click Save and you’ve got your PDF message.
Shut the OneNote window.
