  • Outlook Anywhere isn't working / internal IP traffic not going over HTTPS

    We have a single Exchange 2010 SP1 server running on 2008R2 SP1 that I'm not able to get OA set up for. Testexchange.com returns the following:

    Attempting to ping RPC endpoint 6001 (Exchange Information Store) on server dolly.precor.local.
    The attempt to ping the endpoint failed.
    Tell me more about this issue and how to resolve it
    Additional Details
    The RPC_S_SERVER_UNAVAILABLE error (0x6ba) was thrown by the RPC Runtime process.

    I've set up a sniffer, and I see see traffic going to the internal IP of the mail server port TCP/135. As you can imaging, if I VPN into the network, I am able to connect.

    I did import the server certificate and put a host file entry, but this won't do anything for the traffic not being tunneled.

    Here's what an RPCPing does:

    rpcping -t ncacn_http -s exchange.domain.local -o RpcProxy=mail.domain.com -P "testuser,domain,pwd" -I "testuser,domain,pwd" -H 2 -u 10 -a connect -F 3 -v 3 -E -R none

    Thanks for any guidance.

    Never mind. We've done so much since last Friday the domain and Exchange (including rebuilding Exchange twice), we forgot to re-enable OA the second time. It's working. Thanks
