Hello I ran the Test-OutlookConnectivity -RpcProxyTesttype: External -RpcTestType: Server -Debug to test Outlook Anywhere.....and it fails while pinging RPCProxy with the error below VERBOSE: [22:33:51.597 GMT] Test-OutlookConnectivity : An unexpected exception occurred while pinging RpcProxy. The most common reason for this occurring is that the IIS DefaultAppPool isn't running. Exception: The remote server returned an error: (401) Unauthorized. I have checked IIS 7 and the IIS DefaultAppPool is running ! Is there a way to increase the Verbosity level when running Exchange 2010 cmdlets with the -verbose or -debug parameters that will provide additional diagnostic information ? regards Akinzo

Are you trying to troubleshoot something? How do things look when tested from here: https://www.testexchangeconnectivity.com/

Thanks for your help Yes i tried the https://www.testexchangeconnectivity.com/ first and it fails at the same point too. "RPC Proxy can;t be pinged" with IIS7 Error A Web Exception occured because an HTTP 404-Notfound response was received from IIS7 . Now I have another Internet facing CAS\MBX\Hub Server in the same site and that is currently published via TMG 2010 and that works without any problem. Kind Regards Akinzo
