How do I find the Email Internet Headers?

Internet Headers will contain valuable information to figure out what routes did that email take to get to you. Including the server info of where it was sent from. Generally IP addresses and Protocols used.

Copy those and send them as well to support@precision-computer.com when you have a suspicious email.

Outlook, open the email, Navigate to Message -> Tags and click little square with arrow pointing out to expand options. And look for popup box that has "Internet Headers", select and copy everything inside then click to forward the email, paste it inside and send to support.

After pasting it, just click send
