Hi,
i have 4 exchange servers running, 2x Client Access, 2x MAilbox with DAG.
i configured the external URL on all virtual directories and outlook anywhere to cas.contoso.com
the internal url is cas01.contoso.com and cas02.contoso.com.
All Clients connect from outside the company, so the internal url doesn't matter.
When i client connects from outside, it's very slow. I saw on the firewall, that outlook is trying to connect to cas01 or cas02.contoso.com and then gives up and go to cas.contoso.com which is right.
how can i check, why outlook is trying to access the servers instead of the alias cas.contoso.com ?
cas.contoso.com points to KEMP Load balancers which distribute the load to the two Client access servers.
