Showing message headers and source used to be easy in early Outlook versions.
But as of Outlook 2007 they hid the internet message headers even further away than in Outlook 2003.
Steps for Outlook 2007+:
- Start Outlook.
- Double-click the message for which you want to view full internet headers.
- Click Options (2007) or Tags (2010/2013).
- The Message Options dialog box is displayed. You are after the Internet headers field at the bottom of the dialog box.
Same for the message source:
- Start Outlook
- Double-click the message for which you want to view full internet headers.
- In the Move section of the Ribbon, click on Actions
- Click Other Actions
- Click View Source
- Notepad (or the program associated with html source files) opens with a file email.txt containing the message source.
