So, one of the challenges of learning something is that even when the answer appears to be in a forum, one is not certain that is applies to a simple question - so please bear with me here.
When I export a RTF into Word, my hyperlinks–to external, valid URLs–do not remain hyperlinks Is that expected behavior?
Your links might still be there. Over here, links in RTF’s opened in Word are not underlined or blue – but hovering the mouse shows they are there and active because the cursor changes to the pointed finger, and the link is clickable. If you select the text where the link is supposed to be, choose “Toggle Field Codes” in the contextual menu and the HYPERLINK field should be displayed wherever there is a link.
