How do I report Hotmail with full headers included? If you need to report an e-mail to an authority or organisation, then include the full header so that action can be taken. Sign in to Hotmail, click Options (next to help) and select Mail from the left-hand panel, followed by Junk E-Mail Protection. On the following screen select Mail Display settings. Under Message Headers select Full and then click OK. You will now be able to forward mail with full headers displayed.
