How to View Internet Headers

Last reviewed on December 30, 2013   —  17 comments

The method depends on the version of Outlook. With the exception of Outlook 2003, Outlook displays only the headers, not the full message source. If viewing headers is something you need to do often, use a utility or VBA code to view and copy the headers.

Beginning with Outlook 2003, you can view the header and full message source together by adding the SaveAllMIMENotJustHeaders value to the registry. For more information and ready-to-use reg files, see View the Message Source in Outlook

For a more readable copy of the Internet headers in Outlook 2007, 2010, or 2013, use a VBA macro to create a readable copy the headers in a new message form. Get the code sample from Get Outlook’s Internet Headers using VBA.

    I do find it interesting that MS changed how to view full headers in 2010. Yes, lets open emails that you are concerned about and used to be able to see the header information prior to open. This does not seem very smart in the real world. I would rate this change as a -200 on a 1-10 scale.

    Hi Diane, related to this, do you (or does anyone there) know how to search emails for text in the headers, using the Advanced Find feature in Outlook?

    Some may know that we can create rules based on values in headers, but there's no option for "message headers" in the Advanced Find feature, which many folks on the web have asked about, yet no one's ever answered.

    Does anyone at Slipstick (or anyone at all) know if there's a way to get it to work? It would be really valuable.

    (Let me add that some on the web have misunderstood this question, thinking that this is asking for a way to search individual headers. That's not necessary at all. We would be happy simply to search among all the headers in each message (which not much text at all, as Diane's entry above will help anyone see if they've not noticed before).

    Thanks for any thoughts.

    In previous versions of Outlook you didn't have to open a message first -- that's dangerous! If you want a message's headers, it's usually because the message is suspect, so you DON'T want to open it. Now you have to! Who at Microsoft was PAID to make THAT idiotic decision??

    I have outlook 2010 and neither the expamd button nor the file/properties worked - nothing there about showing headers.

    The instructions you give for Outlook 2010 are not valid. Out of the box, no changed ribbon etc., 2010 does not have an expend button in the Tags menu, nor does it have a "Properties" selection in the File menu. Possibly 2013 does have these things, I can't check as although we tried 2013 we have removed it; it was too problematic.

    I was trying to expend the header to check on the origin of some spam, but unlike previous versions and other mail clients, I cannot find a way to do this in 2010. More Microsoft failure. I had to load the email into another mail client to look at headers.

    Cheers

    I wish I had looked for this sooner. And I am sorry I didn't get in on this. I checked who EMails were from using the Option in earlier than 2010 at home and at work (work for a government agency). Because of the many contacts I make in the business world, I don't always recognize what shows in the unopened messages from. Now I just have to dump a message if I don't readily identify it as I have no choice. If an application is already in the older software what does it take to be in the newer packages?

    This helped mask the bad decision someone made but it took me awhile to find the QAT! It is the ROW of objects at the top most left, for those that use then scream when they can't find stuff and then read the manual.

    In Outlook 2007 you could check the internet headers without actually opening the message. This was a good way to check suspicious emails and delete them without having to open the contents of the message. Having to open the message to check the internet headers is a serious security flaw in Outlook 2010 and 2013

    Thank you very much - i wanted an easy way to view message headers in Outlook 2010 and this is exactly the information I needed!

    Does not seem to work in Outlook 2013 - no "message properties" in list.
