String cMSExchangeWebServiceURL = (String)System.Configuration.ConfigurationSettings.AppSettings["MSExchangeWebServiceURL"]; String cEmail = (String)System.Configuration.ConfigurationSettings.AppSettings["Cemail"]; String cPassword = (String)System.Configuration.ConfigurationSettings.AppSettings["Cpassword"]; String cTo = (String)System.Configuration.ConfigurationSettings.AppSettings["CTo"];

            ExchangeServiceBinding esb = new ExchangeServiceBinding();
            esb.Timeout = 1800000;
            esb.AllowAutoRedirect = true;
            esb.UseDefaultCredentials = false;


            esb.Credentials = new NetworkCredential(cEmail, cPassword);
            esb.Url = cMSExchangeWebServiceURL;
            ServicePointManager.ServerCertificateValidationCallback += delegate(object sender1, X509Certificate certificate, X509Chain chain, SslPolicyErrors sslPolicyErrors) 

            { 

                return true; };

            // Create a CreateItem request object
            CreateItemType request = new CreateItemType();


            // Setup the request:
            // Indicate that we only want to send the message. No copy will be saved.
            request.MessageDisposition = MessageDispositionType.SendOnly;
            request.MessageDispositionSpecified = true;

            // Create a message object and set its properties
            MessageType message = new MessageType();
            message.Subject = subject;
            message.Body = new TestOutgoingEmailServer.com.cogniti.mail1.BodyType();
            message.Body.BodyType1 = BodyTypeType.HTML;


            message.Body.Value = body;

            message.ToRecipients = new EmailAddressType[3];

            message.ToRecipients[0] = new EmailAddressType();
            //message.ToRecipients[1] = new EmailAddressType();
            //message.ToRecipients[2] = new EmailAddressType();

            message.ToRecipients[0].EmailAddress = "[email protected]";
            message.ToRecipients[0].RoutingType = "SMTP";


            //message.CcRecipients = new EmailAddressType[1];
            //message.CcRecipients[0] = new EmailAddressType();
            //message.CcRecipients[0].EmailAddress = toEmailAddress.ElementAt(1).ToString();
            //message.CcRecipients[0].RoutingType = "SMTP";


            //There are some more properties in MessageType object 
            //you can set all according to your requirement
            // Construct the array of items to send
            request.Items = new NonEmptyArrayOfAllItemsType();
            request.Items.Items = new ItemType[1];
            request.Items.Items[0] = message;

            // Call the CreateItem EWS method.
            CreateItemResponseType response = esb.CreateItem(request);
