To trace an email problem, the most important information is contained in the mail headers. These are little pieces of code that tell us who sent it, what servers processed, and what the errors were.

Forwarding an email as an attachment is what any mail admin will as you for.

Forward an Email as an Attachment in Outlook

To forward an individual message in its full and original state — attached as an EML file (which some email programs such as OS X Mail may display inline) including all header lines — in Outlook using the ribbon and buttons:

  • Open the message you want to forward in the reading pane or in its own window.
    • You can also merely highlight the email in the message list.
    • To forward multiple messages as attachments at once (and in one email), make sure they are all highlighted in the message list.
      (Use search to get all the desired emails in one place.)
  • If the message is open in your Outlook’s reading pane:
    • Make sure the HOME ribbon is selected and visible.
  • If the message is open in its own window:
    • Make sure the MESSAGE ribbon is selected and visible.
  • Click More (or the More Respond Actions icon if only that is visible) in the Respond section.
  • Select Forward as Attachment from the menu that has appeared.

To forward a message as an attachment using the keyboard shortcut:

  • Open the email you want to forward in the preview pane or in its own window, or, to forward multiple messages in one go, make sure they are all highlighted in the message list for the folder or in search results.
  • Press Ctrl-Alt-F.

Save email as attachment then send new mail

You can also save the original email as an attachment to your desktop and add it to a new email as an attachment (clever huh).
