The underlying code of an email message in Microsoft Outlook can be examined to reveal the message’s technical details. This process allows users to see the raw format, including headers, routing information, and the HTML or plain text content before it is rendered in the email client. For example, analyzing the source can display the sender’s IP address, the path the email took across servers, and any hidden tracking pixels embedded within the message.
Accessing this data is important for verifying the authenticity of emails and identifying potential phishing attempts or spam. The information contained within provides valuable insight into the origin and integrity of the message. Historically, this capability has been essential for system administrators and security professionals to troubleshoot email delivery issues and investigate malicious activity.
