How to send a message reply with attachments

Question

Is it possible to add attachments when using "message reply"?

We send replies on an message using the message reply statement below:

"POST /users/{id | userPrincipalName}/mailFolders/{id}/messages/{id}/reply"

Now we also would like to send attachments with our replies. Is it possible in the same post statement, or is there an other way to do this?

Hi @TWS

I'm glad to hear you solve the problem, if you have any issue about MS Graph Booking, you are welcome to raise a ticket in this forum.

By the way, since the Microsoft Q&A community has a policy that "The question author cannot accept their own answer. They can only accept answers by others." and according to the scenario introduced here: Answering your own questions on Microsoft Q&A, I would make a brief summary of this thread:

How to send a message reply with attachments

Solution:

Providing the file details under attachments property in request payload, able to send the attachments while replying to the message using MS Graph API.

{
  "message": {
    "subject": "Test reply",
    "toRecipients":[
      {
        "emailAddress": {
          "address":"******@test.com",
          "name":"name"
        }
      }
     ],
	"attachments": [
      {
        "@odata.type": "#microsoft.graph.fileAttachment",
        "name": "attachment1.txt",
        "contentType": "text/plain",
        "contentBytes": "SGVsbG8gV29ybGQh"
      },
      {
        "@odata.type": "#microsoft.graph.fileAttachment",
        "name": "attachment2.txt",
        "contentType": "text/plain",
        "contentBytes": "SGVsbG8gV29ybGQh"
      }	  
    ]	
    },	
    "comment": "reply 123456"
}

Am I really to understand that to enable "reply all with original attachments," someone has to add a JSON file to our Office build? That will certainly never happen in an org my size.

MS Office has a million features no one uses, and this is not built in as a native option to toggle on and off somewhere in mail settings? I can't decide whether to ... not believe this ... or just accept it as par for the course per MS.

OK, I'm glad I decided not to believe this. I just opened the message, right clicked the orignal attachment and copied it, hit Reply All and then right-click paste and there is my attachment.
