I am building a solution using the Microsoft Graph API where the goal is to retrieve the internet headers of the parent email (the email being replied to). After sending a mail, it appears in my "Sent" folder, and I am trying to reply to it. I am unable to fetch the internet headers for the parent email, which is critical for propagating important information through my add-in. I tried using both `.select('internetheaders')` as well as fetching raw message and parsing the MIME content. I can however fetch the internet headers using the recipient's account. when the mail is in Inbox folder. This issue is a significant blocker as it prevents the correct propagation of essential security information needed for the add-in to function properly. I would appreciate any resolution or workaround **as soon as possible** to address this issue. Adding the sender to the recipients list is one possible workaround, but I prefer not to use it as it's not a conventional approach.
