Question

我在Office 365中找不到与Microsoft Graph API邮件消息（https://developer.microsoft.com/en-us/graph/docs/api-reference/v1.0/resources/mail_api_overview）检索有关的信息。如果邮件已加密，该怎么办，我仍然可以检索它吗？可以公开哪些元数据和数据？

如果邮件已加密，会发生什么情况，我仍然可以找回它吗？什么是元数据和数据暴露

是的，您仍然可以检索消息列表，但是不能通过Graph API获取实际的消息正文。邮件 Body / BodyPreview 将显示如下：

此消息受Microsoft信息保护保护。您可以使用Microsoft Outlook（适用于iOS，Android， Windows和Mac OS。在这里获取适用于您设备的Outlook： http://aka.ms/protectedmessage。 Microsoft信息保护a

我的测试请求字符串：

https://graph.microsoft.com/v1.0/me/messages?$filter=startswith(subject,'Data Protected mail test')&top=1

响应数据（元数据供您参考）：
