I have a problem with Sending a Bookmark hyperlink through outlook.

I have a large word document saved on a publicly shared server. I want
to be able to link the Bookmark to an email and send out to people
internally so that they can get directly to the section they need to be
in. When I test the bookmark before I send, it works fine. However
after I send I get a message from outlook about only opening
attachments from a trustworthy source and then it goes to the top of
the page. This happens even if I send the email to myself.

HELP!
