Hi am in the process of upgrading my EXCH 2007 to 2010 (not 2013 :( ). to isaolate my two new servers (hosting all 3 roles) i have created a new test AD site and moved the servers to that. Exchagne servers was installed before the AD site was changed. A CAS array was created before the AD site was changed.
I have made sure the RpcClientAccessServer attribute for each database points to the internal FQDN of the CAS array and i can i ahve created two DNS A records with a low TTL with CAS Array name pointing to the IPs of the exchange servers.
When i profile my test Outlook client (in my live AD site not the test site) i put in the CAS array name and it resolves to one of the servers. it should stay as the cas array name but it doesnt.
Any auggestions.
