How to get the attachment of an item attachment using microsoft graph api?

Question

我想检索邮件中的附件&这封邮件本身是另一封邮件的附件。我正在使用微软图形api。我使用了项目附件api，它将提取邮件，但如果邮件有附件。如何获取附加电子邮件的附件？

Answer 1

When emails are attached to other emails, the name of the attachment is usually the subject name of the attached email. You could fire off another Microsoft Graph request with a filter clause specifying that name as the subject. You can then repeat this process to get to the inner attached email and so forth.
