In previous versions of Microsoft Outlook (the classic app), you could view the HTML code of an email by opening the email, right-clicking on it, and selecting “View source” from the context menu.

Running an HTML code via Notepad in Windows 11/10 is a super easy task. If you are not sure how, well, you are in the right place.

To find the HTML code, you need to have the Web page open in your browser. Go to "Tools," select "Web Developer" and click "Page Source" in Mozilla Firefox to see your Facebook HTML.
