使用WebDAV从Exchange下载附件

Question

我一直在尝试使用WebDAV从Exchange 2003服务器中的邮件中检索附件。

我可以成功阅读邮件并查看附件列表。但是我无法保存附件。在这两种情况下，错误是：

“远程服务器返回错误：< 403>故宫

任何想法，我做错了 我的代码：？

 static void Main(string[] args) 
    { 

     HttpWebRequest Request; 
     WebResponse Response; 
     CredentialCache MyCredentialCache; 
     string attachment = "http://mailserver/Exchange/Username/Inbox/Test.EML/Test.txt"; 
     string strUserName = "username"; 
     string strPassword = "password"; 
     string strDomain = "domain"; 

     try 
     { 
      // HttpWebRequest 
      MyCredentialCache = new System.Net.CredentialCache(); 
      MyCredentialCache.Add(new System.Uri(attachment), "NTLM", new NetworkCredential(strUserName, strPassword, strDomain)); 

      Request = (HttpWebRequest)HttpWebRequest.Create(attachment); 
      Request.Credentials = MyCredentialCache; 
      Request.Method = "GET"; 
      Response = (HttpWebResponse)Request.GetResponse(); 
     } 
     catch(Exception ex) 
      { 
       Console.WriteLine(ex.Message.ToString()); 
      } 

     try 
     { 
      //Web Client 
      string downloadPath = "D:\\Downloads"; 

      WebClient wcClient = new WebClient(); 
      wcClient.Credentials = new NetworkCredential(strUserName, strPassword, strDomain); 
      string file = Path.GetFileName(attachment); 
      string filename = Path.Combine(downloadPath, file); 
      wcClient.DownloadFile(attachment, filename); 
     } 

     catch (Exception ex) 
     { 
      Console.WriteLine(ex.Message.ToString()); 
     } 

     Console.ReadLine(); 

    }
