If you search the MSKB for mailto (I don't know why I didn't keep the article number in the code) it may give more detail about what's needed. I seem to recall a couple month back that someone using Netscape didn't have a mailto: entry so maybe Netscape internally handles the mailto links on a page.

>>David I also came across a machine that has outlook/exchange installed but can not run the mailto command. Is there a way I can check for the ability to run the mailto: command before I execute it. As I was assuming (and you know what that gets you) that if outlook was installed then the mailto: command would work.

Thanks again, I will check the MSKB for any other helpfull hints
