Outlook - Setting a internet header on send and getting it on reply/forward
Hi,
I am creating an Office JS Add-In for Outlook and I have an existing COM Add-In solution that sets an internet header when an email is sent and then it is able to get it when the email is replied to or forwarded.
But when I tried applying that to my Office JS Add-In I was able to set and see that the received email has that internet header set but when replying or forwarding the email I have no way of accessing it using the Office.InternetHeaders interface.
I used the getAsync and setAsync from the Office.InternetHeaders.

Is what I am trying to do possible in Office JS?
