A family of Microsoft word processing software products for creating web, email, and print documents.
I "think" version 15.27 corrects this problem. I run the fast insider release and the "best for electronic...) comes up now on my Save As dialog when I choose PDF. I must use File > Save As and choose the Export Format PDF choice.
Then the option appears on the Save As dialog
None of this will occur if I choose any PDF option from the File > Print dialog.
I said, "I think" this is fixed in the 15.27 release because back in August when I had the insider 15.26 release, I was not seeing this option at all. I did not pay attention if it got fixed during any September updates while I've been running 15.27. However, yesterday I was pushed a new update, which signifies the eminent release of 15.27 publicly and there's a "What's New..." message that PDF enhancements for maintaining links has been made.
Why you've got one machine showing the feature and another not and if both are running the same release... that's a mystery. I believe the MAU (Microsoft Automatic Update) messes up periodically and not all updates get loaded.
The only other final thing I can suggest is try logging in and out of your subscription. Both computers have subscription version of the software don't they? If one's a permanent license, that might be somehow related to the problem.
