I have deployed owa Sign in and Signout page in Exchange 2010 Env.
I applied in all the CAS server and able to get new owa page in Internal office network.
When i check from Outside of my office network.. I was able to get the signin page in owa and the signout page is not showing the exact one. the signout page shows like signout page and added as its secured by threat management gateway.
I have OWA published in TMG. so how to change the signout page for external network.
Do i need to do any changes in TMG or its normal that it will show as Secured by Threat management gateway when publishing owa in TMG.
