Has anyone tried to use OWA as a default mail client on an end user machine? This would best be described as setting OWA to open a new message or even prompt the user to log in when a mailto link is clicked in a web page. A good example of this would be hotmails use of this feature. Since there is no installation on a users machine to use OWA, I can't see how this could be accomplished without some sort of third party software. Thanks!
