Exchange 2013 Outlook Anywhere error

Hello,

I am trying to configure Outlook Anywhere for Exchange 2013 (Version 15.0 Build 516.32) on Windows Server 2012. It is a NEW installation. The CAS server is separated from the MBX servers. The CAS server is behind a NAT on port 443. The MBX servers are not reachable via internet.

I have already tryed uninstalling/reinstalling the RCP over HTTP role, also deleting the RPC web application. Following are the errors and the configurations of the CAS server. Trying to connect with Outlook 2010 sp2 fully patched on Win7 pro fully patched doesn't work.

Any ideas?

Thank you very much!

Marco

The testexchangeconnectivity.com website gives me only this error (everything else is ok):

You didn't set public OA name (ExternalHostname attribute):

Hi,

Several checkpoints:

  1. OA proxy server name must be resolvable on the Internet. It always uses the OWA name.
  2. Aotudiscover.domain.com must be resolvable on the Internet.
  3. Above two host names must be included in the certificate.

Thanks,
