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)：

DEBUG: setDebug: JavaMail version 1.4.4

现在我得到了“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");

解决方法:

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