如何連接到Exchange？

Question

我想在我的公司中最簡單的事情就是檢索郵件。我試圖通過Imap - 沒有成功，（ImapX根本不連接，沒有顯示錯誤），我來到EWS。

但也有一些voo-doo魔術參與。 這裏是有一些錯誤代碼：

 ExchangeService service = new ExchangeService(ExchangeVersion.Exchange2007_SP1); 
     service.TraceEnabled = true; 
     service.TraceFlags = TraceFlags.All; 
     service.UseDefaultCredentials = true; 

     service.Url = new Uri("https://some.com/EWS/Exchange.asmx"); // The request failed. Unable to connect to the remote server 
     var folder = Folder.Bind(service, WellKnownFolderName.Inbox); 

     ///////////////////another try 
     ExchangeService service = new ExchangeService(ExchangeVersion.Exchange2007_SP1); 
     service.TraceEnabled = true; 
     service.TraceFlags = TraceFlags.All; 
     service.UseDefaultCredentials = true; 

     service.AutodiscoverUrl("someone@some.com"); // Discover server not found 
     var folder = Folder.Bind(service, WellKnownFolderName.Inbox); 

不過，我能連接到WSDL版本：

 ExchangeService service = new ExchangeService(ExchangeVersion.Exchange2007_SP1); 
     service.TraceEnabled = true; 
     service.TraceFlags = TraceFlags.All; 
     service.UseDefaultCredentials = true; 

     service.Url = new Uri("https://some.com:444/EWS/Services.wsdl");//Wow! It worked. 
     var folder = Folder.Bind(service, WellKnownFolderName.Inbox);//duh, Method Not Allowed ........ 
     return null; 

如何赫克我連接到EWS？我可以通過Outlook進行連接，並從我的域帳戶的Autodiscover.xml文件中獲取所有地址。這個問題吹了我的腦袋。

UPDATE

這裏是例如與IMAP服務器：

var client = new ImapX.ImapClient("imap.some.com", 993, true); 
client.Connect(); //just do nothing. nothing is connected, no errors.

確保已autodisocver配置EWS web服務。使用Microsoft測試連接工具來分析交流發現設置：

Answer 2

public static class ExchangeServerService 
{ 
    // The following is a basic redirection validation callback method. It 
    // inspects the redirection URL and only allows the Service object to 
    // follow the redirection link if the URL is using HTTPS. 
    private static bool RedirectionUrlValidationCallback(string redirectionUrl) 
    { 
     // The default for the validation callback is to reject the URL. 
     bool result = false; 

     Uri redirectionUri = new Uri(redirectionUrl); 

     // Validate the contents of the redirection URL. In this simple validation 
     // callback, the redirection URL is considered valid if it is using HTTPS 
     // to encrypt the authentication credentials. 
     if (redirectionUri.Scheme == "https") 
     { 
      result = true; 
     } 

     return result; 
    } 

    public static ExchangeService ConnectToService() 
    { 
     try 
     { 
      ExchangeService service = new ExchangeService(ExchangeVersion.Exchange2010_SP2); 
      service.Credentials = new NetworkCredential(@"email", "password"); 
      service.AutodiscoverUrl(@"email", RedirectionUrlValidationCallback); 

      return service; 
     } 
     catch (Exception ex) 
     { 
      // log exception maybe 
      return null; 
     } 
    } 
} 

這樣使用它：

var ESserver = ExchangeServerService.Connect();
