Remote managment Exchange 2013 SP1 from C# code using Power-Shell.

Question

Hello,
Sorry if I am describing something wrong, but it is first time I am using Microsoft development forum.
I am trying to built library that will manage Exchange remotely using  C# code (VS 2012) and Power-Shell ver.4.0. My workstation and the actual Exchange server physically placed in different domains. In order to test functionalities I am using
user that is member of all administrating and management groups in the appropriative domain. Remote Power-Shell is enabled on Exchange.
In order to connect to the Service I am using that part of code :
internal static bool RedirectionUrlValidationCallback(string redirectionUrl)
bool result = false;
var redirectionUri = new Uri(redirectionUrl);
if (redirectionUri.Scheme.Equals("https"))
result = true;
return result;
internal static ExchangeService ConnectToService(ExchangeVersion version,
string userName,
string emailAddress,
string password,
string domainName,
ref Uri autodiscoverUrl)
ExchangeService service;
try
service = new ExchangeService(version);
service.Credentials = new WebCredentials(userName, password, domainName);
if (autodiscoverUrl.IsNull())
var ads = new AutodiscoverService();
// Enable tracing.
ads.TraceEnabled = true;
// Set the credentials.
ads.Credentials = service.Credentials;
// Prevent the AutodiscoverService from looking in the local Active Directory
// for the Exchange Web Services Services SCP.
ads.EnableScpLookup = false;
// Specify a redirection URL validation
//callback that returns true for valid URLs.
ads.RedirectionUrlValidationCallback = RedirectionUrlValidationCallback;
// Get the Exchange Web Services URL for the user’s mailbox.
var response = ads.GetUserSettings(emailAddress, UserSettingName.InternalEwsUrl);
// Extract the Exchange Web Services URL from the response.
autodiscoverUrl = new Uri(response.Settings[UserSettingName.InternalEwsUrl].ToString());
// Update Service Url
service.Url = autodiscoverUrl;
else
service.Url = autodiscoverUrl;
catch (FormatException fe) // The user principal name(email) is in a bad format. UPN format is needed.
LoggingFactory.LogException(fe);
return null;
catch (AutodiscoverLocalException ale)
LoggingFactory.LogException(ale);
return null;
catch (Exception e)
LoggingFactory.LogException(e);
return null;
return service;
Then I am trying to reach existing mailbox of that user, using this part of code :
try
var runSpace = getRunspace();
var pwShell = PowerShell.Create();
pwShell.Runspace = runSpace;
var command = new PSCommand();
command.AddCommand("Get-Mailbox");
command.AddParameter("Identity", userPrincipalName);
command.AddParameter("RecipientTypeDetails", recipientType);
pwShell.Commands = command;
var result = pwShell.Invoke();
if (result.IsNotNull() && result.Any())
// TODO : fill appropriative DTO and return it.
else
// TODO : send back appropriative error.
closeRunSpace(runSpace);
catch (Exception e)
// TODO : log the exception and send back appropriative error.
private Runspace getRunspace()
var runSpaceConfig = RunspaceConfiguration.Create();
var runSpace = RunspaceFactory.CreateRunspace(runSpaceConfig);
PSSnapInException snapEx;
var psInfo = runSpaceConfig.AddPSSnapIn("Microsoft.Exchange.Management.PowerShell.E2010", out snapEx);
runSpace.Open();
return runSpace;
private void closeRunSpace(Runspace runSpace)
runSpace.Close();
runSpace.Dispose();
With this part I had problem. I received exception that appropriative Snap-in is not installed on my computer. I had no installation disk of Exchange in order to install Management Tool (as I understand this is the way to add needed part) so I changed run
space activation to that part of code :
private Runspace getRunspace()
var newCredentials = (PSCredential)null;
var connectionInfo = new WSManConnectionInfo(new Uri("http://exchange.domainname.local/powershell?serializationLevel=Full"),
"http://schemas.microsoft.com/powershell/Microsoft.Exchange",
newCredentials);
connectionInfo.AuthenticationMechanism = AuthenticationMechanism.Kerberos;
var runSpace = RunspaceFactory.CreateRunspace(connectionInfo);
runSpace.Open();
return runSpace;
Now I am receiving exception :
"Connecting to remote server exchange.domainname.local failed with the following error message :
[ClientAccessServer=exchange,BackEndServer=exchange.domainname.local,RequestId=....,TimeStamp=...]
Access is denied. For more information, see the about_Remote_Troubleshooting Help topic."
Please help me to understand what I am doing wrong.
Thank you.
Alexander.

In Exchange 2010 you should be using Remote Powershell not local powershell and the snap-in.  Here is a sample that may help you:
