使用javamail对邮件office 365的IMAP访问

Question

我试图使用JavaMail1.4 API阅读电子邮件帐户Office365文件夹中的电子邮件。

    public static void main(String argv[]) throws Exception {
    // Get a Properties object
    Properties props = System.getProperties();

    // Get a Session object
    Session session = Session.getInstance(props, null);

    // Get a Store object
    Store store = null;
    Folder rf = null;

    if (CUR_MAIL_PROTOCOL != null)
        store = session.getStore("imap");

    // Connect
    if (CUR_MAIL_HOST != null || CUR_MAIL_LOGIN != null || CUR_MAIL_PWD != null)
        store.connect("outlook.office365.com", 993, "**MYEMAIL**", "**MYPASS**");
    else
        store.connect();

    // List namespace
    rf = store.getDefaultFolder();

    getFolderDetails(rf, true, "");
    if ((rf.getType() & Folder.HOLDS_FOLDERS) != 0) {
        Folder[] f = rf.list("%");
        for (int i = 0; i < f.length; i++)
            getFolderDetails(f[i], recursive, "    ");
    }

    store.close();
}

    Exception in thread "main" javax.mail.MessagingException: Connection timed out: connect;
  nested exception is: 
    java.net.ConnectException: Connection timed out: connect
    at com.sun.mail.imap.IMAPStore.protocolConnect(IMAPStore.java:298)
    at javax.mail.Service.connect(Service.java:234)

Answer 1

在我的情况下，缺少的是：

 props.setProperty("mail.imaps.sasl.mechanisms","XOAUTH2")

所有为我工作的道具（gmail和o365):

"mail.imaps.ssl.enable"         true
"mail.imaps.sasl.enable"        true
"mail.imaps.auth.login.disable" true
"mail.imaps.auth.plain.disable" true
"mail.imaps.auth.mechanisms"    "XOAUTH2"
"mail.imaps.usesocketchannels"  true
"mail.event.scope"              "session"
"mail.imaps.starttls.enable"    true
"mail.imaps.sasl.mechanisms"    "XOAUTH2"
