javax.mail.AuthenticationFailedException：验证失败。 IMAP 商店未连接

Question

我无法连接到 IMAP 商店。它现在工作得更早，低于错误

javax.mail.AuthenticationFailedException: AUTHENTICATE failed.
    at com.sun.mail.imap.IMAPStore.protocolConnect(IMAPStore.java:474)
    at javax.mail.Service.connect(Service.java:275)
    at javax.mail.Service.connect(Service.java:156)
    at javax.mail.Service.connect(Service.java:176)

代码：

Properties properties = new Properties();
properties.put("mail.imap.host", "outlook.office365.com"));
properties.put("mail.imap.port", "993");
properties.setProperty("mail.imap.socketFactory.class", "javax.net.ssl.SSLSocketFactory");
properties.setProperty("mail.imap.socketFactory.fallback", "false");
properties.setProperty("mail.imap.socketFactory.port", String.valueOf("993")));
session = Session.getInstance(properties);
store = session.get("imap");
store.connect(username,password);

我检查了所有链接，我尝试了一些建议的解决方案，但它们都没有用。

Answer 1

身份验证失败错误即将到来，因为该帐户的 Imap 未在防火墙上启用。

Answer 2

创建一个应用程序密码并使用 it.It 即可，而不是提供普通密码。

步骤登录 Office 365 获得我的帐户-->安全和隐私-->额外的安全验证-->创建和管理应用密码

仅使用以下属性

Properties props = new Properties();
props.put("mail.imap.host", "outlook.office365.com");
props.setProperty("mail.imap.starttls.enable", "true");
props.setProperty("mail.imaps.port", "993");
props.setProperty("mail.debug", "true");

Answer 3

我在最近升级的outlook office365帐户中读取邮件时也遇到了这个问题。

我更改了代码以使用 microsoft ews-java-api 并解决了问题。

使用 microsoft ews-java-api 建立连接并阅读带有附件和传递主题的电子邮件的示例代码：

import microsoft.exchange.webservices.data.core.ExchangeService;
import microsoft.exchange.webservices.data.core.PropertySet;
import microsoft.exchange.webservices.data.core.enumeration.misc.ExchangeVersion;
import microsoft.exchange.webservices.data.core.enumeration.property.WellKnownFolderName;
import microsoft.exchange.webservices.data.core.enumeration.search.LogicalOperator;
import microsoft.exchange.webservices.data.core.service.item.EmailMessage;
import microsoft.exchange.webservices.data.core.service.item.Item;
import microsoft.exchange.webservices.data.core.service.schema.ItemSchema;
import microsoft.exchange.webservices.data.credential.ExchangeCredentials;
import microsoft.exchange.webservices.data.credential.WebCredentials;
import microsoft.exchange.webservices.data.property.complex.FileAttachment;
import microsoft.exchange.webservices.data.search.ItemView;

import microsoft.exchange.webservices.data.core.service.folder.Folder;
import microsoft.exchange.webservices.data.search.filter.SearchFilter;
import org.springframework.util.CollectionUtils;

import java.net.URI;
import java.util.ArrayList;
import java.util.List;

public class ExchangeEmailTest {
    public static void main(String[] args) {
        try {
            ExchangeService service = createConnection();
            readAttachmentEmail(service);
        } catch (Exception e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
    }

    private static ExchangeService createConnection() throws Exception {
        String email = "your email";
        String password= "your email password";
        ExchangeService service = new ExchangeService(ExchangeVersion.Exchange2010_SP2);
        ExchangeCredentials credentials = new WebCredentials(email, password);
        service.setUrl(new URI("https://outlook.office365.com/EWS/Exchange.asmx"));
        service.setCredentials(credentials);
        return service;
    }

    private static void readAttachmentEmail(ExchangeService service) throws Exception {
        // Bind to the Inbox.
        Folder inbox = Folder.bind(service, WellKnownFolderName.Inbox);
        // set number of items you want to retrieve
        ItemView view = new ItemView(1);
        List<SearchFilter> searchFilterCollection = new ArrayList<>();
        // flag to pick only email which contains attachments
        searchFilterCollection.add(new SearchFilter.IsEqualTo(ItemSchema.HasAttachments, Boolean.TRUE));
        searchFilterCollection.add(new SearchFilter.ContainsSubstring(ItemSchema.Subject,"subject filter"));
        SearchFilter finalSearchFilter = new SearchFilter.SearchFilterCollection(LogicalOperator.And, searchFilterCollection);
        ArrayList<Item> items =  service.findItems(inbox.getId(), finalSearchFilter, view).getItems();
        if(!CollectionUtils.isEmpty(items)) {
            Item item= items.get(0);
            System.out.println("id==========" + item.getDateTimeReceived());
            System.out.println("sub==========" + item.getSubject());
            EmailMessage message = EmailMessage.bind(service, item.getId(), new PropertySet(ItemSchema.Attachments));
            FileAttachment attachment = (FileAttachment) message.getAttachments().getItems().get(0);
            attachment.load(" < attachment save directory > "+attachment.getName());
        }

    }
}

Answer 4

当我尝试运行不同设备中的代码时，我遇到了与 gmail 帐户相同的问题。这是因为 google 不允许 gmail 帐户登录到其他设备。解决方案为此，您应该允许使用以下 url 访问该帐户：

https://accounts.google.com/DisplayUnlockCaptcha
