Microsoft Graph邮件消息加密

Question

我无法在Office365中找到与Microsoft (overview)检索加密邮件消息有关的信息。如果邮件被加密了，我还能取回它吗？哪些元数据和数据可以公开？

如果邮件被加密了，我还能取回它吗？哪些元数据和数据可以公开？

是的，您仍然可以检索消息列表，但是不能通过Graph获得实际的消息体。邮件Body/BodyPreview将显示如下：

此消息受到Microsoft信息保护的保护。您可以使用Microsoft打开它，它可用于iOS、Android和Mac。在这里为您的设备获取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(供参考的元数据)：
