问题描述
我有以下代码应该通过IMAP打开与Microsoft Exchange服务器的连接：
+--------------------+-------------+---------------+----+--------------------+--------------------+
| Metadata_key| datehour| sequence|desc| raw_sequence| quality|
+--------------------+-------------+---------------+----+--------------------+--------------------+

Folder inputFolder = null;
Folder doneFolder = null;
Store store = null;
Properties properties = new Properties();
Session emailSession = null;
properties.put("mail.imaps.host",imapHost);
properties.put("mail.imaps.user",mailUsername);
properties.put("mail.imaps.port",Integer.toString(imapPort));
properties.put("mail.imaps.starttls.enable","true");
MailSSLSocketFactory sf = new MailSSLSocketFactory();
sf.setTrustedHosts(new String[]{"XXXXXXXXX"});
properties.put("mail.imaps.socketFactory",sf);
properties.put("mail.debug","true");
logger.info(String.format("Using user name '%s'",mailUsername));
try {
emailSession = createEmailSession(properties);
store = getStore(emailSession);
store.connect(mailUsername,mailPassword);
是主机名。
XXXXXXXXX和createEmailSession方法如下：
getStore Store getStore(final Session emailSession) throws NoSuchProviderException {
return emailSession.getStore("imaps");
}
Session createEmailSession(final Properties properties) {
return Session.getInstance(properties);
}
导致以下错误消息：
store.connect(mailUsername,mailPassword)调试输出如下：

和相应的密码）。然后我开始收到这样的消息。我与管理员交谈，他们告诉我，由于使用错误密码登录的尝试过多，用户已被锁定。他们还说他们已经解锁了用户，并且应该可以正常工作。
但事实并非如此。
根据上面的调试输出，如何缩小问题范围？
更新1：根据this页，当我使用YYYYYYYYY时，Exchange服务器仅支持Kerberos和NTLM身份验证。也许这就是它失败的原因。
更新2： This answer建议使用ews-java-api访问Exchange Server。会尝试的。
更新3：禁止使用
进行纯文本身份验证PLAIN没有帮助。
