When I convert my word document to a pdf the links no longer work. How do I fix this?

I'm having this same problem.  When I convert a Word Document with hyperlinks included to a PDF the links work at first in the PDF document, but a few minutes later something happens and they disappear and are completely gone from the document.  I followed your instructions and my Adobe Acrobat Pro is already set to "Create links from URLs" and the Microsoft Office is already checked to "Add links to PDF Files"

I am using Office 365 and Acrabat Pro but it says Adobe Acrobat X Version 10.0.0

I have noticed that after I have saved a PDF document I get a little red dot on the document icon.  I have looked into that a little further and the document ends up being in protected mode.  I remove the protected mode but by then the links are all gone and I have to start over.  I don't know how to change so that it doesn't default to protected mode and delete all my links.  I'm not even sure these two instances are related, but it seems to be.  Only my pdfs that end up with that little red dot on the icon end up with all the links being gone.  

Do you know of a way to resolve this issue?  My IT department has tried to help several times but I keep getting the same problem.
