Question

我需要通过IMAPS JavaMail连接到Microsoft Exchange Server。首先，我得到了：

A1 NO AUTHENTICATE failed.
javax.mail.AuthenticationFailedException: AUTHENTICATE failed.

我的调试器中的

异常。

然后，我禁用了一些身份验证协议：

imapProps.setProperty("mail.imaps.auth.plain.disable", "true");
imapProps.setProperty("mail.imaps.auth.ntlm.disable", "true");
imapProps.setProperty("mail.imaps.auth.gssapi.disable", "true");

这是我得到的新例外（我附上了整个日志）：

现在我收到了“NO LOGIN failed”异常。

这是我的完整代码：

Properties imapProps = new Properties();
imapProps.setProperty("mail.imaps.socketFactory.port", "993");
imapProps.setProperty("mail.imaps.starttls.enable", "true");
imapProps.setProperty("mail.imaps.socketFactory.class", "javax.net.ssl.SSLSocketFactory");
imapProps.setProperty("mail.imaps.socketFactory.fallback", "false");
imapProps.setProperty("mail.imaps.auth.plain.disable", "true");
imapProps.setProperty("mail.imaps.auth.ntlm.disable", "true");
imapProps.setProperty("mail.imaps.auth.gssapi.disable", "true");
imapProps.setProperty("username", "user@domain.com");   
imapProps.setProperty("password", "password");

String host = "host.domain.com";
int port = Integer.parseInt("993");

Authenticator authenticator = new Authenticator() {
    protected PasswordAuthentication getPasswordAuthentication() {
        return new PasswordAuthentication("user@domain.com", "password");
    }
};

session = Session.getInstance(imapProps, authenticator);

session.setDebug(true);

Store store = session.getStore("imaps");

store.connect(host, "user@domain.com", "password");

Answer 1

您需要使用支持NTLM身份验证的较新版本的JavaMail。最新版本为1.5.1。

另请参阅此common mistakes列表。

Answer 2

如果用户名和邮件ID相同，它将进行锻炼。

例如：系统用户名为john，邮件ID为john@test.com

IMAP尝试使用来自john@test.com的用户名“ john”登录邮件ID，如果用户ID不同则将无法登录。

Answer 3

尝试使用您自己的身份验证器

public class ExchangeAuthenticator extends Authenticator {

    String username;
    String password;

    public ExchangeAuthenticator(String username, String password) {
        super();
        this.username= username;
        this.password= password;
    }

    public PasswordAuthentication getPasswordAuthentication() {
        return new PasswordAuthentication(username, password);
    }
}

并在您的代码中添加

session = Session.getInstance(props,new ExchangeAuthenticator(username, password));

使用Javamail访问Microsoft Exchange邮箱（IMAP，MS Exchange）
