I have Exchange 2013 CU3 installed and i'm using TMG server for authentication. I am able to login through OWA but when i try to logoff it shows me message of "Close All your Browser Windows.." but OWA does not sign out.
On TMG, only Basic and NTLM authentication is supported. And in IIS Authentication for the OWA Virtual Directory is set to basic.
Can anyone please help me for TMG settings for exchange server 2013? Thankyou for the answers.
