I have a 2 Node CAS Array, with our e-mail server address resolving to a VIP on our F5 load-balancer.
I want to introduce a third CAS server, but prevent it from being discovered by Outlook clients.
The goal is to use a separate mailbox server, CAS server and third party software to import mail data from an EDB file into mailboxes residing on a database on this mailbox server. Using MAPI RPC-TCP/IP current testing of this process appears to reveal a bottleneck of this traffic going through our load-balancer to a CAS server.
I bypassed the load balancer by specifying one of the CAS servers using a local HOSTS file, this improved the speed of the import process. I believe it can be further more improved by having a dedicated CAS server for this process, but wouldn't want my Outlook users connecting to it. Is a better option to not have Autodiscover configured on the new CAS server, and instead use Outlook Anywhere for this process? Would that impact my current user environment?
Thank you in advance.
