OWA Log-Off Page

I've recently set up an APM profile which allows external access to OWA. I am able to get into my mailbox just fine, with no issues. I currently have it set up so that when I click "logout", I am returned to a banner message. What I would like to set up is when I click "logout", I am directed to a webpage that displays "You have been successfully logged off". Also, upon doing this, all cookies and active session info is deleted. Does anyone know a way I can go about doing this?
