Hey I searched around and havent found many post on using ISA 2006 and smart card log in for webmail for Exchange 2007. I wrote a document on how we were able to get it working. Hope this will help anyone else out that may be having issues. http://thedigitalpostman.blogspot.com/2009/07/cac-enabled-login.html

Thanks for your sharing.Mike

Yes, thank you! I was just beginning to try and figure out how to do this as well. This will be very helpful!Jim McBee - Blog - http://mostlyexchange.blogspot.com
