We are using Microsoft Graph API to send and receive emails. Just like outlook, during a reply is composed, we want to change, remove or add new recipients. However, MS graph api of replyall or reply does not allow changing any email address.
How can we achieve this functionality using MS Graph API ?
You should use create-reply endpoint https://docs.microsoft.com/en-us/graph/api/message-createreply?view=graph-rest-1.0&tabs=http
That will create a draft reply message (and return the Id for that) that you can then patch any way you want including updating the recipient addresses and replyto then you send that draft message.
