Assuming a vanilla POP3 account in Outlook, how does one get the Message-ID: header of sent email?

Alternatively, the raw MIME object as submitted to the SMTP server would be equally valuable. E. g. a way of making Outlook dump every message it sends into a text file.

This concerns Outlook 2013+. The problem is some ERP system sending email via MAPI which appears to generate defective MIME structures. Customer claims “it did work before!”

(There are numerous how-tos online that point to the menu „File → Properties → Internet Headers“ but the version of Outlook I have access to, it shows no headers there at all.)

As far as I know, there should be message internet headers no matter which version you have(Outlook 2010-365). Please make sure you open the message in a new window first, then click File > Properties, here you can see the internet headers.

  • Thanks for pointing out that it’s not enough to select the message; when I open the message I now get that “Properties” menu. However, the “Internet Headers” field is empty and grayed out. No Message-Id: there. – phg May 05 '20 at 07:41
