Some people who attempt this are having issues with certificates and credential promtps, is there anything I'm missing in terms of security configuration?Īgree with Steve, we need to create a CAS array.

External access is handled by UAG so don't have to change anything on at tip either.Ħ. The only thing that is worrying me is autodiscovery.ĥ. So I'm assuming don't have to change web services configuration. Both servers are installed with CAS, Hub Transport and Mailbox roles and the web services are configured the same way it suggests in this Create a new A Record on my DNS server pointing the CAS Array domain to the virtual IP address on the load balancer.ĥ. Add all databases to this newly created CAS Array through the management shell.Ĥ. Create a CAS Array with a unique FQDN such as using the Exchange Management Shellģ.

This is what I have in mind, anything I've missed?ġ. So not sure if I want to proceed with this (though I should really) but say I do, what would be the steps? Would I have to add any other SANs to the existing certificate? Any other things I needīad news, looks like I will have to go to each client machine to correct the Exchange address on Outlook. But how do I point my clients to the virtual ip internally? DNS? If so what A record would have to create? How does the SSL certificateīusiness work? What SANs would I need? I have, and ofcourse the external access domain on my current SSL certificate. I can setup a virtual ip on the load balancer using the RPC port and add both exchange servers as nodes.
What do I need do in my environment to achieve load balancing for the CAS? This is not happening, some of my clients connect using MX1 and Ideally, the clients that get disconnected, should automatically connect to their mailboxes using the other MX2. MX1 get disconnected and cannot connect until MX1 is up and running. Let's say I restart MX1, the clients that are connected to their mailboxes through I'm using DAG in my Exchange environment, so databases are highly available, however the CAS servers are not internally balanced and this is where I need some advise. The SSL certificate is installed on the F5 load balancer, the UAG servers and the Exchange servers. I've added all my Exchange servers as web servers to the UAGĪpp and published OWA over the DMZ.
The external client access domain is pointing to this virtual ip. Created a virtual ip on the load balancer and added both servers as nodes. I've setup two UAG servers within the DMZ zone. Incoming SMTP traffic is load balanced between the two servers using the load balancer. OWA and external client access using a UAG cluster Two Exchange Servers: MX1 and MX2, both installed with CAS, Hub Transport and Mailbox roles I'm looking to load balance my CAS servers using a F5 Big IP load balancer.
