是否可以使用 OWA rest-api 从 SENT 项目中获取电子邮件 header？

Question

根据这个问题通过

GET https://outlook.office.com/api/beta/me/mailfolders/inbox/messages$select=InternetMessageHeaders

但是我只能获取收件箱的 header ，我还需要检索已发送的邮件的 header！

Answer 1

The email headers are created by the email servers, these details can include who sent the message, the software that was used to compose it, and the email servers that it passed through on its way to the recipient. Hence you are not able to view the header information for the sent messages.

Answer 2

可以使用$value参数获取邮件的MIME类型，读取整个邮件头！

来自Example 4 - Get message

GET https://graph.microsoft.com/v1.0/me/messages/4aade2547798441eab5188a7a2436bc1/$value
