如何正确读取 Microsoft Graph 发送的电子邮件文件夹？

我正在尝试阅读我的电子邮件已发送文件夹。

GET https://graph.microsoft.com/v1.0/me/mailfolders('outbox')/messages

在Graph Explorer 中，我总是得到一个空数组：

{
    "@odata.context": "https://graph.microsoft.com/v1.0/$metadata#users('16f5a7b6-5a15-4568-aa5a-31bb117e9967')/mailFolders('outbox')/messages",
    "value": []
}

当我跑

GET https://graph.microsoft.com/v1.0/me/mailfolders

只有已发送文件夹（发件箱）显示 0 封电子邮件，但实际上文件夹中有电子邮件。

如何正确读取已发送文件夹？谢谢
