I am working with web application and we are using QTP now.
My application functionality is, if you process the 
application, one email will go in to the "OUTLOOL EXPRESS".
In that mail one url link is visible. If you click on the 
link,it will open the application.
My problem is i need to test the GUI on the application.
we need to open the email through QTP script.
is it possible? If possible,please give me answer.
