通過EWS連接到Outlook收件箱時出錯

Question

在發佈之前，我已經經歷了類似的帖子，但找不到解決方案。我正在嘗試使用EWS API閱讀我的Outlook收件箱，但我一直收到401訪問被拒絕的錯誤。請幫幫我。

我已經設置了用戶名，密碼和域名按照API的需要，但不知道爲什麼會出現401

public final class ExchangeServerConnection { 

    private static String exchangemailurl; 

    private static String userName; 

    //private static String password; 
    private ExchangeServerConnection() { 

    } 


    public static ExchangeService connectionEWS(String string) { 
     // TODO Auto-generated method stub 
     { 
      ExchangeService service = null; 
      try { 
       service = new ExchangeService(ExchangeVersion.Exchange2010_SP2); 
       ExchangeCredentials credentials = new WebCredentials("username@comp.com", "Uddsa#2k16", null); 
       service.setCredentials(credentials); 
       service.setUrl(new URI("https://email-domain.com/ews/Exchange.asmx")); 
      } catch (URISyntaxException e) { 

      } 
      return service; 
     } 
    } 
} 

主要類：

public class EmailUtil { 
    public static void main (String args[]) throws Exception{ 

     ExchangeService service = ExchangeServerConnection.connectionEWS("Uaua#2k16"); 
     System.err.println("Connections has been set up"); 
     FolderView view1 = new FolderView(EWSConstants.TEN.getNumber()); 
     System.err.println("1"); 
     // ExtendedPropertyDefinition isHiddenProp = new ExtendedPropertyDefinition(EWSConstants.PRODDEF.getNumber(), 
     // MapiPropertyType.Boolean); 
     System.err.println("2"); 
     //PropertySet pr1 = new PropertySet(BasePropertySet.IdOnly, FolderSchema.DisplayName, isHiddenProp); 
     // view1.setPropertySet(pr1); 
     System.err.println("3"); 
     view1.setTraversal(FolderTraversal.Deep); 
     System.err.println("4"); 
     SearchFilter searchFilter1 = new SearchFilter.IsEqualTo(FolderSchema.DisplayName, EWSConstants.INBOX.getValue()); 
     System.err.println("5"); 

     searchFilter1 = new SearchFilter.SearchFilterCollection(LogicalOperator.Or, searchFilter1); 
     System.err.println("6"); 
     FindFoldersResults findFolderResults = service.findFolders(WellKnownFolderName.MsgFolderRoot, searchFilter1, view1); 
     System.err.println("7"); 
     Folder folder = findFolderResults.getFolders().get(0); 
     System.err.println("8"); 
     folder.load(); 
     System.err.println(folder.getTotalCount()); 
     int messageCount = folder.getTotalCount(); 
     System.err.println("message count is "+messageCount); 

    } 
}

是憑據正確形成？它看起來像你試圖連接一個電子郵件地址，而不是用戶/域對。它是否有助於改變

ExchangeCredentials credentials = 
    new WebCredentials("username@comp.com", "*pass*", null); 

到

ExchangeCredentials credentials = 
    new WebCredentials("username", "*pass*", "comp.com"); 

或

ExchangeCredentials credentials = 
    new WebCredentials("username", "*pass*", "*name.of.domain.the.exchange.server.is.on*");
