Hello everyone,
I’m retrieving Office 365 mails using the Graph API. I can retrieve the Message ID with ease. The object (Office365Message.Headers.Keys.Count) returned zero headers. My objective is to retrieve the Internet Headers’ In-Reply-To field. I verified that the field was filled in using Outlook -->Email → Properties.
I’ve already looked at forum articles that call for using marketplace activities to turn the object into a mail item. Using third-party activities for the project is prohibited.
I am unable to use the traditional GetOutlookemail message activity since I am retrieving emails from many accounts. Regards
