用于IMAP和SMTP身份验证的Office 365 XOAUTH2失败

Question

最近support for OAuth 2.0 for IMAP and SMTP in the Exchange Online已经宣布。在the guide之后，我设置了应用程序权限以及IMAP和SMTP连接。该应用程序被配置为Accounts in any organizational directory (Any Azure AD directory - Multitenant)，并使用authorization code flow。

以下URL用于授权：

并且已添加以下委托的Microsoft Graph范围：

范围，来自代码的请求：

final List<String> scopes = Arrays.asList(
    "offline_access",
    "email",
    "openid",
    "profile",
    "User.Read",
    "Mail.ReadWrite",
    "https%3A%2F%2Foutlook.office365.com%2FIMAP.AccessAsUser.All",
    "https%3A%2F%2Foutlook.office365.com%2FSMTP.Send"
);

我已成功接收访问和刷新令牌：

{
    "token_type": "Bearer",
    "scope": "email IMAP.AccessAsUser.All Mail.ReadWrite openid profile SMTP.Send User.Read",
    "expires_in": 3599,
    "ext_expires_in": 3599,
    "access_token": "edited",
    "refresh_token": "edited",
    "id_token": "edited"
}

这是用于连接到IMAP的代码：

Properties props = new Properties();
props.put("mail.imap.ssl.enable", "true");
props.put("mail.imaps.sasl.enable", "true");
props.put("mail.imaps.sasl.mechanisms", "XOAUTH2");
props.put("mail.imap.auth.login.disable", "true");
props.put("mail.imap.auth.plain.disable", "true");
props.put("mail.debug", "true");
props.put("mail.debug.auth", "true");

Session session = Session.getInstance(props);
session.setDebug(true);

String userEmail = "[email protected]";
String accessToken = "access_token_received_on_previous_step";

final Store store = session.getStore("imaps");
store.connect("outlook.office365.com", 993, userEmail, accessToken);

将生成以下输出：

并且以下代码用于连接到SMTP：

Properties props = new Properties();
props.put("mail.smtp.auth", "true");
props.put("mail.transport.protocol", "smtp");
props.put("mail.smtp.starttls.enable", "true");
props.put("mail.smtp.auth.mechanisms", "XOAUTH2");
props.put("mail.smtp.auth.login.disable","true");
props.put("mail.smtp.auth.plain.disable","true");
props.put("mail.debug.auth", "true");

Session session = Session.getInstance(props);
session.setDebug(true);

String userEmail = "[email protected]";
String accessToken = "access_token_received_on_previous_step";

Transport transport = session.getTransport("smtp");
transport.connect("smtp.office365.com", 587, userEmail, accessToken);

哪个提供以下输出：

我也尝试过的：

将范围指定为https://graph.microsoft.com/SMTP.Send，仅指定SMTP.Send
使用https://login.microsoftonline.com/common/网址进行身份验证

结果始终相同。

是我做错了事，还是Microsoft方面对此提供支持的地方出现错误？

更新1：

从命令行尝试，但结果相同：

$ openssl s_client -crlf -connect outlook.office365.com:993

更新2：

尝试使用以下权限在Azure门户中创建全新的应用程序：

并且在尝试同意范围时会收到以下屏幕：

这很奇怪，因为来自Azure Portal的权限未指定需要征得管理员同意，并且当请求IMAP和SMTP范围时，我先前的应用程序注册也不会显示该屏幕。
