Can Groupwise be default Windows email A

I currently have Groupwise 5.2 as our company-wide email client. I need to be able to set Groupwise as the “default” email program through INTERNET OPTIONS/PROGRAMS.

Right now my only choices are Outlook, LotusMail and Hotmail. Groupwise is notevenin the dropdown menu… Any solutions for me on this one? (i searched Novell but my eyes grew tired with the irrelavent search results).
