通過Java中的Pop3閱讀Outlook 365的INBOX時面臨錯誤

Question

我有要求從Outlook 365帳戶的INBOX文件夾中讀取電子郵件。 我已經安裝了所有必需的證書，並且可以通過我的機器遠程登錄outlook.office365.com主機。

我使用的是JDK 1.6.0.29版本，我的Outlook 365對POP3和IMAP使用TLS 1.0加密。

不過還是我得到下面的錯誤 -

javax.mail.AuthenticationFailedException: EOF on socket 
    at com.sun.mail.pop3.POP3Store.protocolConnect(POP3Store.java:209) 
    at javax.mail.Service.connect(Service.java:386) 
    at client.ConnectToOffice365REST.check(ConnectToOffice365REST.java:56) 
    at client.ConnectToOffice365REST.main(ConnectToOffice365REST.java:96) 

這裏是我完整的代碼 -

package client; 




    import java.util.Properties; 

import javax.mail.Authenticator; 
import javax.mail.Folder; 
    import javax.mail.Message; 
    import javax.mail.MessagingException; 
    import javax.mail.NoSuchProviderException; 
import javax.mail.PasswordAuthentication; 
import javax.mail.Session; 
    import javax.mail.Store; 

    public class ConnectToOffice365REST{ 
     public static String username =null; 
     public static String password1 =null; 
     public static void check(String host, String storeType, String user, 
      String password) 
     { username= user; 
      password1 = password; 
      try { 



      //create properties field 
      Properties properties = new Properties(); 

      properties.put("mail.pop3.host", host); 
      properties.put("mail.pop3.port", "995"); 
      properties.put("mail.pop3.starttls.enable", "true"); 
       properties.setProperty("mail.pop3.socketFactory.fallback", "false"); 
       properties.setProperty("mail.pop3.socketFactory.port",  
         String.valueOf("995")); 
       properties.put("mail.pop3.auth", "true"); 
       properties.put("mail.debug.auth", "true"); 
      Session emailSession = Session.getDefaultInstance(properties); 





      //create the POP3 store object and connect with the pop server 

      Store store = emailSession.getStore("pop3"); 
     // store.connect(host, user, password); 
      // store.connect(host, 995, user, password); 

      //create the folder object and open it 
      Folder emailFolder = store.getFolder("INBOX"); 
      emailFolder.open(Folder.READ_ONLY); 

      // retrieve the messages from the folder in an array and print it 
      Message[] messages = emailFolder.getMessages(); 
      System.out.println("messages.length---" + messages.length); 

      for (int i = 0, n = messages.length; i < n; i++) { 
      Message message = messages[i]; 
      System.out.println("---------------------------------"); 
      System.out.println("Email Number " + (i + 1)); 
      System.out.println("Subject: " + message.getSubject()); 
      System.out.println("From: " + message.getFrom()[0]); 
      System.out.println("Text: " + message.getContent().toString()); 

      } 

      //close the store and folder objects 
      emailFolder.close(false); 
      store.close(); 

      } catch (NoSuchProviderException e) { 
      e.printStackTrace(); 
      } catch (MessagingException e) { 
      e.printStackTrace(); 
      } catch (Exception e) { 
      e.printStackTrace(); 
      } 
     } 

     public static void main(String[] args) { 

      String host = "outlook.office365.com";// change accordingly 
      String mailStoreType = "pop3"; 
      String username = "username";// change accordingly 
      String password = "password";// change accordingly 

      check(host, mailStoreType, username, password); 

     } 

    } 

請讓我知道在哪裏的問題。 1）我必須安裝更多證書嗎？ 2）用戶名和密碼非常好。 3）這是由於TLS而不是SSL加密？

我試過用Google搜索這個錯誤，但沒有找到確切的根本原因？

預先感謝您！
