You should place the CAS servers behind a load balancer. And change the internal/external url's for the servers. For reference you could have a look at this article:

http://www.msexchange.org/articles_tutorials/exchange-server-2010/high-availability-recovery/load-balancing-exchange-2010-client-access-servers-using-hardware-load-balancer-solution-part1.html

Besides this creating a CAS array would be a nice option. This will configure Outlook to connect to the CAS array name instead of a single server which might cause issues in case of a failure.

Regards,
Johan

I have also tested the same scenario with two Servers with CAS+HT+MB role on each and in DAG configuration
exch01.domain.com
exch01.domain.com
and name of DAG is
dag01.domain.com

But for our users what we have done DNS server of user's network we have added an entry as mail.domain.com and gave the IP of dag01.domain.com in this case user is unaware of any HA etc
