ExchangeWebServiceMailBinding Class

Visual Studio 2008

Represents the mail binding for Exchange Web Services.

Namespace:  Microsoft.ServiceModel.Channels.Mail.ExchangeWebService
Assembly:  Microsoft.ServiceModel.Channels.Mail.ExchangeWebService (in Microsoft.ServiceModel.Channels.Mail.ExchangeWebService.dll)

public sealed class ExchangeWebServiceMailBinding : MailBindingBase

This is a sealed class that represents the mail binding that is used to construct an Exchange Web Services transport for the desktop.

The base class, MailBindingBase, contains most of the functionality used by this class.

This class includes a collection of binding elements such as an encoding element and a transport binding element. The predefined encoding element for this class is TextMessageEncodingBindingElement, and the predefined transport binding element is ExchangeWebServiceMailTransportBindingElement.

The desktop computer that is using the Exchange Web Services transport is assumed to be online. Only the mail transport that is used in Windows Mobile devices supports scenarios in which the device might be offline for a while.


This class is included with the .NET Compact Framework version 3.5, but it requires the .NET Framework version 3.0 or later at run time.

The following example shows how to use the ExchangeWebServiceMailBinding class in the context of sending and receiving messages.

The custom serializer is not specific to the Exchange Server mail transport and is not included in this example.

class Program
    private static Uri ServerAddress = new Uri("");
    private static string ClientEmailAddress = "";
    private static string Password = "password";

    private static string ChannelName = "Channel1";
    private static string DestinationEmailAddress = "";

    private static CFMessagingSerializer serializer = new CFMessagingSerializer(typeof(string));

    static void Main(string[] args)
        // For applications on the device, use WindowsMobileMailBinding 
        // instead of ExchangeWebServiceMailBinding.
        ExchangeWebServiceMailBinding binding;
        IChannelFactory<IOutputChannel> factory;
        IChannelListener<IInputChannel> listener;
        IOutputChannel output;
        IInputChannel input;
        BindingParameterCollection bpc;
        Message message;
        string str;

        // For applications on the device, use WindowsMobileMailBinding.
        binding = new ExchangeWebServiceMailBinding(ServerAddress, new NetworkCredential(ClientEmailAddress, Password));
        bpc = new BindingParameterCollection();

        factory = binding.BuildChannelFactory<IOutputChannel>(bpc);
        output = factory.CreateChannel(new EndpointAddress(MailUriHelper.Create(ChannelName, DestinationEmailAddress)));

        message = Message.CreateMessage(MessageVersion.Default, "urn:Test", "Hello, World!", serializer);


        listener = binding.BuildChannelListener<IInputChannel>(MailUriHelper.CreateUri(ChannelName, ""), bpc);
        input = listener.AcceptChannel();

        message = input.Receive();
        str = message.GetBody<string>(serializer);

        Console.WriteLine("Received message: {0}", str);
