Access email via OWA through an ASP page

Hello group,

I am thinking about adding the email feature into my newly
developed ASP page using outlook web access since I don't
want to rely on the local outlook components since some of
the users might not have outlook installed. In fact, I
only need to have the 'send' feature something like this:
when you click the 'mail' button, it trigers OWA and bring
up the email send screen with the 'To' field prefilled.
Please help.

Thanks a lot,
Lilly
