How can I view the source of an email in Outlook 2013?

I want to see the exact email source, as I can do in Gmail or in Mozilla Thunderbird. I'm particularly interested in the top matter (headers?). Here's an example, courtesy Gmail.

  1. Open the particular email in a new window by double-clicking on the message in the message list. (This is important, it's not enough to be just looking at the message in what Outlook calls the 'reading pane'.)
  2. Follow the menu File | Info | Properties
  3. Look for a text area labelled Internet headers
  4. Here are the headers. Select and copy the text to a text editor.


  1. Open message in a new window
  2. On the Message ribbon, select Action | Other Actions | View Source.

    You can also get the Content ("View source") by right-clicking the body of the message and choosing "View source". Jul 31, 2014 at 15:45

    Note that "View source" will be greyed out for text-only messages.

    Note that this only includes the content outlook is displaying. If a email has both html and text, you can't see the text version.

    This one still does not show the embedded base64 images.

    This doesn't show the raw contents of multipart mime attachments.

  3. Select Other ActionsSource

    In Outlook 2013, this gives me the source of the message body, but not the header. Mar 10, 2014 at 3:00

    @HighlyIrregular is correct. All you see is the raw HTML that corresponds to the BODY of the email, but not the internet headers. The accepted answer by colonelPanic is correct.

  • I think the two answers together are correct, one for the headers and the other for the body. Oct 17, 2014 at 11:36
  • In my Outlook 2013 Source is not shown under the Other Actions dropdown. The closest there is [show] Message Headers.

Is File - Info - Properties not working to display the headers?

This answer is from here: email.about.com

Make the complete message source available in Outlook

To set up Outlook so you can see the complete source of emails:

Press Windows-R
Type "regedit".
Hit Enter.
For Outlook 2013:
    Go to HKEY_CURRENT_USER\Software\Microsoft\Office\15.0\Outlook\Options\Mail
Select Edit | New | DWord from the menu.
Type "SaveAllMIMENotJustHeaders".
Hit Enter.
Double-click the newly created SaveAllMIMENotJustHeaders value.
Type "1".
Click OK.
Close the registry editor.
Restart Outlook if it has been running.

See the complete source of a message in Outlook

Now you can retrieve the source of newly retrieved POP messages (editing the SaveAllMIMENotJustHeaders value does not restore the complete message source for emails that were already in Outlook):

Click on the desired message with the right mouse button in the Outlook mailbox.
Select Options... from the menu.
Find the message source under the (now improperly named) Internet headers: section.
  • Thanks Riscie, I followed the instructions and the menu item appeared. However this only shows me the HTML source for the message content, not the top matter or headers. I've clarified my question above. Sep 19, 2012 at 10:22

    @ColonelPanic - The internet header information listed in Message Options is the content your looking for.

    This does not work for me. The "message header" option simply toggles showing the From, To, and Subject at the top of the message. The view source option, and the actions->view in browser then viewing that source, both show the cleaned up HTML by outlook, not the original message source

    This is the only 100% correct answer. Where you could only check message headers, now you can check the whole raw content (attachments, boundaries, resources headers, charsets, etc.) - and this is waaaay different than viewing the message source. Nov 27, 2015 at 0:24

    Hm, probably because meaning it works with POP3 and IMAP accounts only (and EAS in Outlook 2013), not Exchange server mailboxes slipstick.com/outlook/email/view-the-message-source-in-outlook

The add-on Message Header Analyzer for Outlook 2013 and Outlook Online provides a well-formatted overview.

    This shows only headers, not body.
