I've been playing around with graph explorer trying to update emails that already exist in my inbox.
I need to update the message body.
Looking at the API reference, it says that i can only update the subject for draft emails, however i've been able to successfully update the emails in my inbox and change the body content.
So functionality and documentation are mis-matched (or perhaps I didn't understand something)
My question is - can I rely on this behavior? is this a documentation bug? or is this a bug in the graph API?
