How to view email message headers

Every email you receive includes message headers that contain valuable information. You don’t normally need to know what’s in those headers, but when you have email errors, those headers help HostPapa Support figure out what’s wrong.

This article describes how to view email headers in several popular email tools.

    Note: Make sure to be in the pop-up window for a single email message. If you go to the File tab from the main Outlook window, you will not be able to see the Properties button. This process must be done for a specific email message, not for the whole application.
