I've had a look and the 'link to' option does not include a word doc option. I also suspect you have to import docs into the project folder in order to link to them which Last Fudgement did not want to do.
OK but the Word files are on an intranet. So you just link to them using a URL right?
In addition to what others have said, I'll also offer this. Even on a "fast" intranet, a Microsoft Word document can take a long time to open.

Sonny, back in the day when I was a young whippersnapper, when I was in the corporate world, I did the same thing myself. And because opening the document always took longer than most would reasonably expect, I developed a technique that I coined as "docfetch".
I created a separate page in my project for each link. Then linked the TOC to those pages. On the page itself I added some verbiage along the following lines: Please wait as your document is opened.
Then I configured this page to perform a meta redirect that opened the document a second or two later.
This caused the users to stop flooding my inbox to say things were "broke". Also, at that time RoboHelp had issues where it would lose the links to things like documents from the TOC. So it prevented that from happening too.
To configure a meta redirect, just add the following meta tag to your HTML:
<meta HTTP-EQUIV=refresh CONTENT="2;URL=G:\SomeFolder\SomeDocument.DOC">
