Question

我希望通过IMAP从Hotmail接收电子邮件，但我必须通过OAuth进行身份验证。从Microsoft文档中，它支持http://msdn.microsoft.com/en-us/library/dn440163.aspx;

但我必须知道如何在java中使用它（通过Javamail）。我尝试使用谷歌代码示例（正确的电子邮件和access_toket），但失败了。

String email = "stony@hotmail.com";
String oauthToken = "XXXXXXXX";

initialize();

IMAPStore imapStore = connectToImap("imap-mail.outlook.com",
                                    993,
                                    email,
                                    oauthToken,
                                    true);
System.out.println("Successfully authenticated to IMAP.\n");


Folder folder =  imapStore.getDefaultFolder();
folder.open(Folder.READ_ONLY);  //****The linke throw exception****
for (Message msg : folder.getMessages()) {
    String subject = msg.getSubject();
    System.out.println(":" + subject);
}

系统控制台上打印的日志是

Answer 1

我测试成功了！我验证了3件事，

我们可以使用谷歌代码示例收集到Outlook的IMAP。示例代码链接为https://code.google.com/p/google-mail-oauth2-tools/wiki/JavaSampleCode
必须使用范围wl.imap和wl.offline_access
在我的hotmail帐户中没有工作，我甚至无法获得access_token;但在我使用另一个真实账户之后，它就可以了。

Answer 2

您使用的是旧版JavaMail。如果您使用latest版本OAuth2 support is built in。
