How do you view email message source?

How can I view the entire source code of an email in Outlook 2010?

• I know how to view the http://superuser.com/questions/115610 as well as the http://superuser.com/questions/389717. In Outlook Express, however, there was an option to see the http://support.microsoft.com/kb/165531 the exact same way it was received (i.e. headers and any plain-text and/or HTML message parts in the body). Does such an option or something equivalent exist in Outlook 2010?

• Answer:

  To view the headers of a message do the following: In Outlook 2010, Open an existing email. Click on the File tab. Click Info. Click the Properties button. Review the Internet Headers. (To copy: Right-click in the field and click "Select All", right-click again to select copy) In order to view the complete message source code of newly retrieved POP messages in Outlook 2007/2010: Log onto your PC with an administrator account. Open the "Start" menu, type "regedit" into the search field and hit "Enter." The Registry Editor tool will now launch. For Outlook 2007, Navigate to the "HKEY_CURRENT_USER\Software\Microsoft\Office\12.0\Outlook\Options\Mail" directory. OR For Outlook 2010, HKEY_CURRENT_USER\Software\Microsoft\Office\14.0\Outlook\Options\Mail Right-click in the open space on the right side of the window and choose to create a new "DWORD Value." Create a new DWord value and enter "SaveAllMIMENotJustHeaders" as the name of the new value. Double-click on the new value, set the value as "1" and then press "OK" Close the Registry Editor and open Outlook. Right-click on the message whose source code you want to view and select "Message Options." The full source code of the message will now be viewable in the pop-up window that appears.
