How to view Outlook Email Headers (internet headers)

Microsoft hid one really handy and essential feature - the possibility to view message headers. The truth is that it contains a lot of information for you to retrieve.

  • The real address of the sender (not the one you see in the From field since it can be easily falsified). For example, you received an unexpected email from yourbank.com. It looks exactly like all emails you usually get from your bank, still you have doubts… You open the message headers just to see very.suspiciouswebsite.com instead of the sender's server mail.yourbank.com :).
  • The sender's local time zone. It will help you avoid entering Good morning when it is late night on the recipient's side.
  • Email client from which the message was sent.
  • The servers that the email passed. With emails it is just like with letters sent by post. If your and recipient's inboxes are not on the same website, the letter will need to pass some break points. On the Internet their role is played by special email servers that resend the message via third party websites until it finds the recipient. Each server marks the message with its time stamp.
    It can be really entertaining to see that an email from somebody who is in the same room crossed half of the world to get into your inbox.
    It can happen that an email gets stuck within one of the servers. It can be broken or it can fail to find the next third party server. If you don't know about this you can blame the sender who did reply an hour ago. However that happens really seldom.

Each Outlook version keeps email headers in a different location:

View message headers in Outlook 2019–2010

  1. Open the email with the headers you need to see.
  2. Select the Files tab in the email's window.

    Open the needed email and click on the File option

  3. Click on the Properties button.

    Click on the Properties button

  4. You'll get the "Properties" dialog box. In the "Internet Headers" field you'll see all information about the message.

  5. It is 2013 already, but Microsoft haven't made the Properties dialog stretchable and the details are shown in a tiny field. So I suggest clicking within the Internet headers field and then pressing the Ctrl + A keyboard shortcut to copy the information to clipboard. Now you can paste the details to a new Word document or Notepad to have them at a glance.

How to always have the Properties dialog at hand

The Properties box is a really handy option and it would be nice to be able to get it at your earliest convenience. You can use it to add a digital signature to an email, or turn on the option "Do not auto archive this item". With the help of this feature you can also enable such tracking flags as "Request a delivery receipt for this message" and "Request read receipt for this message" to be sure that the email was received.

  1. Go to the File tab and select Options from the left menu list.
  2. In the Outlook Options dialog, pick Quick Access Toolbar.
  3. Select All commands from the Choose commands list.
  4. In the below list find and select "Message options" (you can press M to be able to scroll faster). Please don't make the mistake I made, it is "Message options" you need, not "Options".
  5. Press the "Add >>" button and click OK.

    Press the Add button and click OK

  6. That's it! Now you can see the message headers without opening the email itself and enable the necessary options for the outgoing emails in a few clicks.
