Finding Full Email Headers

When asked to provide full mail headers, we are looking for the header information from the email that tells us when it was sent, and how it was delivered.

Please follow the instructions for your email client below

Outlook 98, Outlook 2000, Outlook 2003

1. Open the message in a separate window (double click)
2. Under the View menu select Options
3. Copy the text in the Internet Headers window (unfortunately it doesn’t include the message itself).
4. Paste
5. Close the options window

Outlook 2007

In Outlook 2007 you can view the headers without opening the message. Just right click on the email message in your Inbox and choose Message Options. This will show you the headers.

Or you can open the email message. You can open the email message by double clicking on it. Outlook 2007 has a new ribbon user interface. Look at the right of Options and you will see an arrow. Click on the arrow and in the bottom section there is the message options menu with internet headers. This will show you the email headers.

Outlook Web Access (OWA)

Left click on the letter you want to open and click on properties
When that opens click on the details tab
Then on message source
This will open the email so the full headers will be available for viewing
Select and copy the text then paste it.

Outlook Express 4, 5 and 6

Start by opening the message in its own window (or when viewing the message in the preview pane). Then:

1. Click the “File” menu
2. Click “Properties”
3. Click the “Details” tab
4. Click “Message Source”
5. Highlight, copy and paste everything from this window (Ctrl-A, Ctrl-C)


Go to “View”
Then go to Headers
and select “All” to  view email headers.

Microsoft Entourage

2. A new window will open showing the full message source with complete headers.
3. Copy and paste

Mac Mail (OS X Mail)

3. Click on the resulting text
4. Click Edit, Select All, then Edit, Copy
5. Paste


Note: Using the cut and paste to the web form method is the only option available to Eudora users. To display the full message source for cut and paste:

Eudora for the Mac:

1. Open the email and click the button on the upper left hand corner of the message. This shows the extended headers.
2. Select the whole message including headers and paste.

Eudora for the PC – there are 2 slightly different methods depending on whether the mail contains HTML or not.

In any case, to prepare for HTML email, you should turn off the use of Microsoft’s HTML viewer. To do so, click Tools, then Options, then Viewing Mail. Uncheck the box labeled “Use Microsoft’s viewer.”

How to know if it’s HTML mail: once you have opened the email, look near the bottom of the headers (see below for revealing headers) for a line like the following: Content-Type: text/html … you can frequently spot HTML email because it has font effects, pictures, etc but this is not always true so you have to take a quick look at the headers.

Eudora for the PC – non-HTML mail:

1. Open the email by double clicking on the subject line. Click the button to reveal the headers.
2. Place your cursor anywhere in the body of the email and select the entire message (Edit/Select All or Ctrl-A)
3. Copy the entire email (right click and click copy OR Ctrl/C OR Edit/Copy)
4. Paste (right click/paste or Ctrl/V).

Eudora for the PC – HTML mail:

1. Open the email and click the button to reveal the headers.
2. Highlight the headers only. Copy and paste the headers.
3. Hit enter twice after the pasted headers to force a blank line after the headers.
4. Back in Eudora window, place your cursor anywhere in the body of the message and right click and click “view source”. A new window will open.
5. In the new window, select all (as above) and copy the contents of the new window.
6. Paste

Pegasus Mail

In the New Mail or other folder window:

1. Right click the message, and select Message Properties.
2. In the right hand column uncheck the box beside Contains HTML data.
3. Click OK. That should allow you to see the message as a text message only.
4. Click Ctrl-H to bring up the full headers.

Another way:

1. Highlight the HTML in the new mail folder
2. Open a new email message
3. Drag the HTML onto the new message
4. In the dialog that appears select “Show All Headers”
5. Highlight the entire message, then copy to clipboard
6. Paste

kmail (KDE Desktop)

In the KDE Mail Client that comes with the KDE desktop for Linux, select Message, View Source. Copy and paste the text from the “Message as Plain Text” window.

GNU/Emacs integrated email

Press the keys ‘W’, then ‘v’ in the summary or mail buffer.

Another method of temporarily switching to ALL headers is by pressing “Ctrl-u g” on the article in the summary buffer.
