Deploying a custom Outlook form as an .oft

I've deployed a .oft file (custom Outlook 2003 mail form) to our LAN so others can access it via a hyperlink off of our intranet. It works great for me but anyone else who trys to open it, just gets a blank e-mail form. I've been told that this will not work, but other forms (created with Outlook 2000) exist that do work. Does anyone have any ideas?

PS: I have deployed the form into the Organizational Forms Library. But the problem remains unless the user launches the form from that Library.
