Exchange 2010/2003 Coexistance Webmail Login Twice Published with TMG
I've seen many other postings about this, but the answer is always to enable SSO on a single listener for both URLs in TMG. That doesn't seem to be working for me. I have a legacy 2003 OWA server and new 2010 CAS server. They are both published
through TMG. Both on the same listener. But I still always have to enter my password twice. They are on 2 separate firewall rules, which from my understanding is correct as each one can only point to a single internal server, but maybe my
understanding of that is not correct. On the SSO tab in TMG, I have Enable Single Signon Checked and my root domain listed in the box. Anyone have any other ideas where to look?
Thanks!

Thanks for the reply. I have followed these instructions already when I did my config. I still have the problem.

Hi Nitin,
To publish with TMG 2010 both 2010 and 2003 mailboxes you can follow my guide,
http://ilantz.wordpress.com/2010/03/12/how-to-publish-exchange-2003-and-exchange-2010-with-isa-2006/
The wizard in TMG includes the directories for 2010 like /ecp , make sure you follow the article and you will be just fine :)
