可以使用ExchangeServiceBinding获取邮件，他相当于outlook, 来获取服务器的未接受的邮件.
至于 “该帐户无权模拟所请求的用户 ” ,是由于在exchange服务器上面没有配置模拟账户.
需要在Exchange Management Shell上执行: New-ManagementRoleAssignment –Name:impersonationAssignmentName –Role:ApplicationImpersonation –User:administrator
见: Configuring Exchange Impersonation:http://msdn.microsoft.com/en-us/library/bb204095.aspx
设置后, 就不会有该帐户无权模拟所请求的用户问题了。
public static int GetUnReadMailCountByUserMailAddress(string UserMailAddress){int unRead = 0;string url = "https://{0}/ews/exchange.asmx";url = string.Format(url, m_ExchangeMachine);try{ExchangeService service = new ExchangeService(ExchangeVersion.Exchange2010_SP1);service.Credentials = new NetworkCredential(m_ServerUser, m_Password, m_Domain);service.Url = new Uri(url);service.ImpersonatedUserId = new ImpersonatedUserId(ConnectingIdType.SmtpAddress, UserMailAddress);unRead = Folder.Bind(service,WellKnownFolderName.Inbox).UnreadCount;}catch (Exception ex){return unRead;throw;}return unRead;}
)
