Just to note, no problem getting active links in TOC when using Save As PDF in Word without Acrobat. That is true with Word 2010, 2013, and 2019 (365). I no longer have 2016 on this computer but it worked with that as well. Note, this is the Save As method, not printing to Microsoft's Print to PDF driver. (I haven't checked that one lately.)



It may take some fiddling with the Options in the save dialog, but I think it is the default.
