Phishing and other email scams are on the rise. One of the best ways to identify fraudulent emails is to examine the email header for detailed information about the sender.. Next, We tell you how to do it in Outlook.
Outlook itself provides a basic view of email headers. If that's not enough, there is a free plugin that breaks down the headers to give you a more human friendly view. We will also cover that.
Basic Outlook header view
To get a basic view of email headers, open the email in Outlook and click File> Properties.
In the Properties window that opens, the header is displayed in the text box “Internet headers” on the bottom.

Despite this, header information is one big block of text, that is not so simple to read, especially if you don't read the headlines very often. For a more useful view, there is a free plugin you can use.
