Viewing message headers in Outlook is a straightforward process, and we believe it’s an essential skill for anyone using email professionally. When we talk about email headers, we’re referring to the detailed route that an email takes from the sender to the recipient, including timestamps, sending and receiving servers, and other technical details. These headers can be particularly useful for troubleshooting issues related to email delivery or for identifying the source of spam or phishing emails.

In our experience, while everyday email users might rarely need to access message headers, understanding how to view them in Outlook can be vital for IT professionals or those mindful of their cyber security. Outlook makes it a relatively simple task to get this information. It’s a matter of a few clicks, and you can reveal a treasure trove of technical data that’s usually hidden from the casual viewer.
When we’re assisting someone in viewing message headers, we always highlight that Outlook has these details tucked away in a place that’s easy to overlook, unless you know where to look. Knowing how to access this information lets us peer into the underlying framework of email exchanges, reflecting the complexity and sophistication of the communication systems we rely on every day.

Accessing Email Headers in Outlook

When exploring email issues or verifying the authenticity of messages, accessing email headers in Microsoft Outlook is a crucial step. These headers contain details about the sender, recipient, and the path the email has taken. Here’s how to view them in the desktop application and Outlook Web Access (OWA).
Outlook Desktop Application
- Open the Microsoft Outlook application on your computer.
- Double-click to open the email in question, taking you out of the Reading Pane.
- Navigate to the File menu.
- Select Properties from the dropdown menu.
Inside the Properties dialog box, you will find a section labeled Internet Headers. You can select, copy, and paste this information elsewhere for more detailed examination.
Outlook Web Access (OWA)
Accessing email headers within OWA can also provide insightful information about your emails.
| Steps for Outlook Web App: |
|
1. Log in to your account via a web browser. 2. Open the email whose headers you want to view. 3. Click the ellipsis (three dots) in the upper-right corner of the message pane. 4. Choose View and then View message details from the dropdown menu. 5. A pop-up will display the email’s header information, which you can copy and paste as needed. |
Both in Outlook for Windows and macOS, as well as in OWA, the Internet Headers provide you with essential details such as the ‘from’, ‘to’, ‘cc’, and the email’s journey across servers. With this knowledge, we can better understand how our emails operate and troubleshoot any issues that may arise.
Understanding Email Headers
Email headers are a crucial aspect of understanding the journey and origins of an email message. They consist of a trail created by servers that handled the email, containing several important pieces of information.
Examining the Components
- Received: The ‘Received’ fields are the most reliable indicators of the email’s path, listing the servers it passed through.
- From: This is the email address of the sender. However, be wary as this can be spoofed.
- To: This shows the intended recipient’s email address.
- CC: Indicates other recipients who were copied into the email.
- Date and Time: Each server transfer adds a timestamp, showing when it processed the email.
- Subject: The topic or title of the email as provided by the sender.
Identifying the Source
The ‘Received’ lines in the email headers are particularly important for identifying the source of an email. We look for the first ‘Received from’ line, which indicates the initial sending server. This is essential for tracing the origin of an email and verifying its legitimacy. In Microsoft Outlook, to view these details, we check the email’s properties, where the header information is located within the “Internet Headers” box. Here, we can analyze whether the email passed through expected servers or identify potential red flags indicating a spoofed email.
Utilizing Message Header Tools
In managing emails, it’s essential for us to view message headers to troubleshoot issues or understand more about the email’s origin and path. A useful tool for this within Microsoft Outlook is the Message Header Analyzer add-in.
Message Header Analyzer Add-In
We use the Message Header Analyzer add-in to get an in-depth look at email header information. This is our go-to utility when we need to view detailed message headers without leaving Outlook. It’s particularly handy in identifying routing issues, verifying sender information, and troubleshooting email problems.
Here’s how we add the Message Header Analyzer to Outlook:
| Step | Action | Note |
| 1. Access Add-Ins | Open Outlook and click on the ‘Get Add-Ins’ tool on the ribbon. | Add-ins option is sometimes found under the ‘Home’ tab. |
| 2. Search | Type “message header” in the search box. | Make sure you’re connected to the internet to search for add-ins. |
| 3. Install | Select “Message Header Analyzer” and click ‘Add’ to install. | The button changes to ‘Added’ once the installation is complete. |
Once installed, we can access the Message Header Analyzer by opening an email message, clicking on the add-in, and viewing the detailed breakdown of the header information. It’s clear and convenient, providing us with crucial information about the email’s route and origins. If necessary, we can even copy this information into Notepad or Word to analyze it further.
Tip: Always verify the actual address of the sender for security purposes, as the visible address might be misleading.
In our experience, understanding an email’s journey and authenticity is much easier with the Message Header Analyzer. It streamlines our workflow and informs our decisions when assessing email validity and safety.
