使用JavaMail访问Microsoft Exchange邮箱（IMAP，微软的Exchange） [英] Use Javamail for accessing Microsoft Exchange mailboxes (IMAP, MS Exchange)

问题描述

我需要连接到通过IMAPS JavaMail的Microsoft Exchange服务器。首先，我得到了：

  A1 NO AUTHENTICATE失败。
javax.mail.AuthenticationFailedException：AUTHENTICATE失败。
 

例外在我的调试器。

然后，我禁用一些认证协议：

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

这是新的异常，我得到（我已经连接了整个日志）：

  DEBUG：setDebug：JavaMail的1.4.4版

在ConnectMail.connectMail（ConnectMail.java:63）
在Main.main（Main.java:9）
 

现在我得到了没有登录失败的异常。

这是我的全code：

 属性imapProps =新特性（）;
imapProps.setProperty（mail.imaps.socketFactory.port，993）;
imapProps.setProperty（mail.imaps.starttls.enable，真）;
imapProps.setProperty（mail.imaps.socketFactory.class，javax.net.ssl​​.SSLSocketFactory）;

};会话= Session.getInstance（imapProps，认证）;session.setDebug（真）;店中店= session.getStore（IMAPS）;store.connect（主机，[e-mail]，密码）;
 

解决方案

您需要使用JavaMail的新版本支持NTLM身份验证。最新的版本是 1.5.1 。

此外，请参阅常见的错误的

I need to connect to a Microsoft Exchange Server through IMAPS JavaMail. First, I got the:

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

exception in my debugger.

Then, I disabled some authentication protocols:

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

This is the new exception I'm getting (I've attached the whole log):

DEBUG: setDebug: JavaMail version 1.4.4
DEBUG: getProvider() returning javax.mail.Provider[STORE,imaps,com.sun.mail.imap.IMAPSSLStore,Sun Microsystems, Inc]

at ConnectMail.connectMail(ConnectMail.java:63)
at Main.main(Main.java:9)

Now I'm getting the "NO LOGIN failed" Exception.

This is my full code:

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", "[e-mail]");   
imapProps.setProperty("password", "password");

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

Authenticator authenticator = new Authenticator() {
    protected PasswordAuthentication getPasswordAuthentication() {
        return new PasswordAuthentication("[e-mail]", "password");
    }
};

session = Session.getInstance(imapProps, authenticator);

session.setDebug(true);

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

store.connect(host, "[e-mail]", "password");

解决方案

You need to use a newer version of JavaMail that supports NTLM authentication. The latest version is 1.5.1.
