Hello,
I am not fully sure about the zen loadbalancer exchange doc but in general: RPC
can be a pain.
Specially outlook is very sensitive for hostname + certificate (if they mis
match it will refuse).
Can you verify:
1) External hostname is properly configured
2) Certificate for the external hostname is valid
3) Direct connection to Exchange without loadbalancer is functioning?
Also what is the method you selected for loadbalancing?
Regards,

Subject: [Zenloadbalancer-support] Issues with Exchange 2010 CAS
Running Zen 3.02 on VMware; 2 Exchange 2010 CAS servers in a CAS array.
Zen was configured per the documentation linked on
zenloadbalancer.org<http://zenloadbalancer.org>, including setting static ports
and SSL offload on Exchange.
I also created farms for ports 6001, 6002, and 6004.
Currently all the Exchange related farms only have one backend server listed.
Everything seems to work except for Outlook Anywhere.
The Remote Connectivity Analyzer shows:
Attempting to ping RPC endpoint 6001 (Exchange Information Store) on server
outlook.domain.com<http://outlook.domain.com>.
The attempt to ping the endpoint failed.
Additional Details
An RPC error was thrown by the RPC Runtime process. Error 1818 CallCancelled
Elapsed Time: 33191 ms.
I know the error 1818 is a timeout; running a similar test internally shows an
error 1722 (RPC_Server_Unavailable).
>From an internal PC I can successfully telnet to 6001 using the Zen farm IP.
