How to get the headers from an email in Outlook Express.
Start by opening the message in its own window (or when viewing the message in the preview pane). Then:
With the keyboard:
CTRL-F3 (Message Source Window)
CTRL-A (select all)
With the mouse:
Click the "File" menu
Click the "Details" tab
Click "Message Source"
Highlight, copy and paste everything from this window (Ctrl-A, Ctrl-C)
With viruses, worms and trojans being spread via email, many users now work with the preview screen in Outlook Express turned off. Viewing the contents of email in the preview screen is no different than opening the message. If the email has malicious content, it may execute in the preview screen.
