Hello All,

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.

We have the same problem by all our customers.

Exchange 2013 CU1 - CU4 with TMG 2010. Do you have a solution now?

Hi,

check the following article:

http://blogs.technet.com/b/exchange/archive/2012/11/21/publishing-exchange-server-2013-using-tmg.aspx

It shows you how to change to logoff-url.

Hi Christian

Thank you for your answer, but we already changed the logoff URL as descripted.

We have the following Problem:

Note: The release of Exchange 2013 RTM CU1 changed the way OWA logoff works, such that the TMG change recommended in this post no longer applies. At the current time there is no way to catch and force logoff at TMG when TMG is generating the form, instead users should be educated to close their browser window (as the pop-up tells them when they click Sign Out from within OWA).

This Problem still not solved with Exchange 2013 CU4.

Cheers,

Thomas Spring

Hello,

I think its by design. if you use TMG then you cannot logoff infact, for security reasons the browser need to be closed and hence you will automatically logged out after closing the browser.

Sorry for very late reply.

I will try this out on my exchange server and will post here my results. Thanks.
