How can I launch Outlook on users machines when they click a button on a web form (InfoPath)?

There is no way to open Outlook directly from the HTML of a web page, nor from the C# "code behind" which is executed on the server running IIS.

If, however, you are programming for your own intranet, or can guarantee that the user is running IE and will execute code from your site with enough privelege, you can write an embedded activeX control and call it from javascript within your page. Because the ActiveX control will download to the client and run there, you can do more or less anything you could do in a normal user program.

Of course, if you write the ActiveX control in C#, you're dependent on the correct version of .NET already being installed on the client machine, too.
