使用Javamail访问微软Exchange邮箱(IMAP,MS Exchange)

6

我需要通过IMAPS JavaMail连接到Microsoft Exchange Server。首先,我获取了:

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

我的调试器发生了异常。

接着,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");

这是我收到的新异常(我已经附上了整个日志):
DEBUG: setDebug: JavaMail version 1.4.4

现在我遇到了“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");

你的代码是完全正确的(一些行可能根本不需要 - 比如认证示例,因为在连接中使用了用户名和密码 - 但不要担心),它能够在我们的交换环境中正常工作。你需要与你们的交换系统管理员进行沟通,因为问题可能来自于那边。 - Miklos Krivan

抱歉更新晚了。是的,这段代码是正确的。问题出在Exchange服务器上。如果有人打算使用它,这段代码是正确的。 - Dilanga Thalpegama
请问您能否描述一下在收到此错误时,您的Exchange服务器遇到了什么问题?谢谢! - ClickerTweeker
很简单,我被提供了错误的凭据。@ClickerTweeker - Dilanga Thalpegama

您需要使用支持NTLM身份验证的新版本JavaMail。最新版本是1.5.1

另外,请查看常见错误列表

如果用户名和邮件地址相同,它将起作用。

例如:系统用户名为john,邮件地址为john@test.com

IMAP尝试使用用户名"john"从john@test.com登录邮件帐户,如果用户ID不同,则无法登录。

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);
    }
}

在你的代码中添加以下内容

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