Microsoft Graph API createReplyAll route returns empty ccRecipients

Question

Hello, I make use of the Microsoft Graph API to receive messages from Outlook and create a draft for reply all. The problem is that the ccRecipients in the response returns an empty array, even there are ccRecipients as shown in the message request below.

This is the request I sent:

POST https://graph.microsoft.com/v1.0/me/messages/{id}/createReplyAll

This is the response I get:

Hi Pieter Uitenbroek,

Thanks for reaching out.

There seems to be an issue with this endpoint. As a work around can you just send a PATCH request to the newly created reply to update the recipients in To and CC fields
