Outlook 2007 tasking in C# with HTML body

Question

Can someone help me figure out how to send a task request with outlook using a C# windows application with an HTML body. I can send e-mail with HTML bodies, and I can send task requests with plain text bodies. I know that you can task with HTML in outlook 2007 because you can do it through the normal user interface. but I cannot figure out how to add HTML bodies to the tasking when doing this through my C# code.

or is there another way that I can send a link in the body of an task? using plain text only if I try to send a link the link recognition ends at the first space, making the link useless.

thanks!
