I have a DC (Server 2012 R2) setup, with RDS and EXCHANGE (with MS Exchange 2013 SP1) as virtual servers.
RDS is facing the internet (mail.domain.com @ Port 443), and is using ARR with URL Rewrite for OWA, EWS, Autodiscover, ActiveSync and ECP, rewriting all requests to EXCHANGE.
When I run tests on https://testconnectivity.microsoft.com
for Outlook connectivity, it fails saying:
Attempting to ping the MAPI Mail Store endpoint with identity: firstname.lastname@example.org:6001.
The attempt to ping the endpoint failed.
Tell me more about this issue and how to resolve it
The RPC_S_SERVER_UNAVAILABLE error (0x6ba) was thrown by the RPC Runtime process.
Elapsed Time: 3310 ms.
Telnet from DC or RDS into EXCHANGE on port 6001 works fine.
However, I am concerned that there may be two things preventing this from working:
m:6001 <-- shouldn't this be trying to connect to mail.domain.com:6001 and not domain.com?
2) Even if there is nothing wrong with the above, I would assume it is using RDS's standard 443 port, and trying to ping 6001 on RDS itself, since as far as I know, URL Rewrite has no rules to forward port requests on to exchange.
Am I right in my assumptions?
