How to Show the Mail Header in Outlook
Find Microsoft Outlook header information from the message’s Properties window. To find it, open the message in a separate window, go to the File tab and select Info, then select Properties.
Using a Different Email Service?
Most email providers and clients let you view a message’s header. You can do this in Microsoft’s email programs and also through Gmail, macOS Mail, Mozilla Thunderbird, and Yahoo Mail.
Headers in Windows Mail
In previous iterations of Windows Mail clients, like Windows Live Mail, features like header details were available, but Microsoft has positioned Windows Mail as a free, ultra-lightweight email client with only the basics. If you’d like to access more advanced header information for your emails, while there are some third-party software solutions for Windows Mail, using an email client like Outlook is easier and simpler.
