Outlook 365 Group vba 循环浏览电子邮件并保存附件

Question

我是名为“报告”的 Outlook 365 组的成员（并设置为所有者之一）。 每天“报告”都会收到带有附件 (xls/csv) 的电子邮件。 在我的 Outlook 应用程序中，我可以看到以下电子邮件：组 > 报告。 我希望 VBA 代码遍历“报告”的所有未读电子邮件，将附件保存在我的计算机上并将电子邮件设置为已读。 我已经为其他 Outlook 文件夹这样做了，这很完美。 我只是无法使用 VBA 访问 Outlook 365 组。 我在网上搜索了一段时间的答案，但找不到解决方案。 非常感谢您的帮助。 您可以在下面找到我的代码（我每天使用）来阅读文件夹 AUTO_REPORT_NWP 中的电子邮件

组不作为存储公开 - 既不在扩展 MAPI 中的MAPISession::GetMsgStoresTable中，也不在 Outlook 对象模型中的Namespace.Folders或Namespace.Stores集合中。 只有通过Application.ActiveExplorer.CurrentFolder在 Outlook 中选择其中一个文件夹时，才能访问这些文件夹之一。
