That did not fix my issue. I have a feeling it has to do with IE8 and SSL sessions. If I go directly to the CAS server I get a cert error but it works like normal. If I use the Netscaler load balancer address I get the multiple authentication and failures. This does not happen with IE6 or IE7.

I had a similar problem and fixed it with a change to the kernel mode authentication in Win 2008: http://blogs.inetium.com/blogs/bjohnson/archive/2009/04/23/windows-2008-and-exchange-2007-cas-servers.aspx -mb From: Senter, John [mailto:john.sen...@etrade.com] Sent: Wednesday, May 13, 2009 5:10 AM To: MS-Exchange Admin Issues Subject: RE: IE8 + OWA2007 = multiple Authentication Kevin, I have the same issue. I have tried IE 8 on my Vista box and Windows 7 box. Go to OWA2007 and login, Inbox shows fine. Click a message and it shows fine in the preview pane, but if I double click the message to open in a new window I get the login screen again. Put in the correct username password, the windows closes and the original session window is now expired and wants me to login again. Since this works fine with IE6 and IE7, I assume there is a security setting causing it, but have not found it yet. From: Michael B.

Longer version of the same Question Problem Statement | I have users across the board with IE8 being prompted for to login every time they open or reply to a message in OWA 2007. On some fun occasions they will open a new message, it will work, only to time out and log them out of the window. Sometimes opening a new message will require that they authenticate to the OWA window and not the message window. Trying to answer so Far | * I've tested this all over the place and it consistently breaks with IE8, and works with IE7. * Compatibility mode has no effect. * The interwebs searches for "IE8 OWA Authentication" did not tell me anything. * I Connected Directly to one of the CAS servers and Bypassed ISA and f5 with the same results.
