I am using the PATCH MS Graph API to modify the email subject/body and I am getting the following error:
"The meeting request has already been sent and might not be updated. (ErrorSentMeetingRequestUpdate)"

I noted that it appears in emails of calendar invitations...

Can you please give some more details of this error, when it happens and how we can avoid it?

Thanks

    @Idan Gazit

    Currently there is no such API to update the Email subject/body this is by design, The API you are trying is to update the messages .
