How to create an Exchange mailbox?

Question

I am trying to create an Exchange mailbox in C#. The following code doesn't produce an error, but it also doesn't appear to create a mailbox as I would expect:

private void buttonCreateUser_Click(object sender, EventArgs e)
{
    Boolean Success = CreateUser(textBoxFirstName.Text, textBoxLastName.Text,
        textBoxAlias.Text, textBoxPassword.Text,
        comboBoxDomain.SelectedItem.ToString(),
        comboBoxOrganizationalUnit.SelectedItem.ToString());

    if (Success)
    {
        labelStatus.Text = "User Created";
    }
    else
    {
        labelStatus.Text = "There Is Some Error";
    }
        
}

public Boolean CreateUser(string FirstName, string LastName, string Alias,
    string PassWord, string DomainName, string OrganizationalUnit)
{
    string Name = FirstName + " " + LastName;
    string PrincipalName = FirstName + "." + LastName + "@" + DomainName;

    Boolean success = false;
    RunspaceConfiguration rsConfig = RunspaceConfiguration.Create();
    SecureString spassword = new SecureString();
    spassword.Clear();

    foreach (char c in PassWord)
    {
        spassword.AppendChar(c);
    }

    PSSnapInException snapInException = null;
    PSSnapInInfo info = rsConfig.AddPSSnapIn(
        "Microsoft.Exchange.Management.PowerShell.E2010", out snapInException);
    Runspace myRunSpace = RunspaceFactory.CreateRunspace(rsConfig);
    myRunSpace.Open();
    Pipeline pipeLine = myRunSpace.CreatePipeline();

    Command myCommand = new Command("New-MailBox");
    myCommand.Parameters.Add("Name", Name);
    myCommand.Parameters.Add("Alias", Alias);
    myCommand.Parameters.Add("UserPrincipalName", PrincipalName);
    myCommand.Parameters.Add("Confirm", true);
    myCommand.Parameters.Add("SamAccountName", Alias);
    myCommand.Parameters.Add("FirstName", FirstName);
    myCommand.Parameters.Add("LastName", LastName);
    myCommand.Parameters.Add("Password", spassword);
    myCommand.Parameters.Add("ResetPasswordOnNextLogon", false);
    myCommand.Parameters.Add("OrganizationalUnit", OrganizationalUnit);
    pipeLine.Commands.Add(myCommand);
    pipeLine.Invoke();
    myRunSpace.Dispose();
  
    success = true;

    return success;
}

I don't get an error, so I don't know what I am doing wrong.

Update

I am using Web Service For this.If I run same code with windows application it works,But not with WebService? should I make any change in Exchange Server? Though I can Get information of MailBox with Get-MailBox but New-MailBox not Creating User.
