You cannot provide just the
idof the message. If you do that, you'll get a blank attachment. Unfortunately the API is not set up to retrieve the item by ID and insert it for you.So what that means is you need to retrieve the message yourself and include that entire JSON payload in the
itemproperty of the attachment. (See https://developer.microsoft.com/en-us/graph/docs/api-reference/v1.0/api/message_post_attachments)There is one key detail that you need to be aware of: before adding the JSON representation of the message to be attached, you need to add an
@odata.typeproperty to it, and set it tomicrosoft.graph.message.For example:
Get the message to be attached
GET /me/messages/{id}Response
