Part # 2 - Using C#.Net & Exchange Web Service (EWS) : How to create and send e-mail messages?

In this we will see how to create & send e-mail messages using Exchange Web Service (EWS). It’s pretty simple with EWS to do.

        // Create the Exchange Service Binding

         ExchangeServiceBinding esb = new ExchangeServiceBinding();

        // Add its relevant Credentials like user name, password, domain and URL

         esb.Credentials = new NetworkCredential(userName, Password, domain);

         esb.Url = @"https://myexchangeserver/EWS/Exchange.asmx";

         // CreateItemType and set its relevant properties/values

         CreateItemType request = new CreateItemType();

         // Select Message Disposition specified

         request.MessageDisposition = MessageDispositionType.SendOnly;

         request.MessageDispositionSpecified = true;

        // Create MessageType and set its relevant properties/values

         MessageType message = new MessageType();

         // Enter value for subject

         message.Subject = subject;

         message.Body = new BodyType();

         message.Body.BodyType1 = BodyTypeType.Text;

        // Enter value for body

         message.Body.Value = body;

         message.ToRecipients = new EmailAddressType[1];

         message.ToRecipients[0] = new EmailAddressType();

        // Enter ToEmailAddress

         message.ToRecipients[0].EmailAddress = toEmailAddress;

        // Select Routing Type

         message.ToRecipients[0].RoutingType = "SMTP";

         request.Items = new NonEmptyArrayOfAllItemsType();

         request.Items.Items = new ItemType[1];

         request.Items.Items[0] = message;

         try

         {

            CreateItemResponseType response = esb.CreateItem(request);

            // Determine whether the request was a success.

             if (response.ResponseMessages.Items[0].ResponseClass == ResponseClassType.Error)

             {

                 throw new Exception(response.ResponseMessages.Items[0].MessageText);

             }

             else

             {

                 Console.WriteLine("Item was created");

                 Console.Read(); 

             }

           }

           catch(Exception e)

             {

                 Console.WriteLine(e.Message);

                 Console.Read();

             }

Try this code snippet. Happy programming!!
