ExchangeService service = new ExchangeService(ExchangeVersion.Exchange2007_SP1);  
var assembly = Assembly.GetExecutingAssembly();
                    byte[] bytes = xyz.Properties.Resources.Template;


                    TinyUser tu = new TinyUser("r7929");
                    EmailMessage newMessage = new EmailMessage(service);


                  
                    newMessage.SetExtendedProperty(binaryProperties, bytes);
                    


                    tu.EMail = newMessage.ToRecipients.Add("niad@outlook.com").ToString();

                    Absence ab = ServiceLookup.APServerProxy.GetAbsence(842);
                    Absences abs = new Absences();
                    abs.Add(ab);

                    UsersAbsences usa = new UsersAbsences();
                    usa.Add(ua);

                    Console.WriteLine("Absence of (842");
                    AccreditorUsersAbsences aua = new AccreditorUsersAbsences(tu, usa);

                    TinyUser tua = new TinyUser("r7929");

                    aua.Accreditor = tua;

                    MailManager.Instance.SendMailToAccreditor(aua);
                    newMessage.Subject = "Request for vacation";
                    newMessage.Body = new MessageBody("Email Body");
 newMessage.Send();
