How to Find IP Address of Email Sender in Outlook (Trace Email)

Every email we send and receive has metadata with the information about the particular email. The metadata provides routing and other useful details about the email. It is called an ‘email header’ in most email programs. Every email application and the client has different ways to view the email header information. Let’s look at how to find the IP address of an email sender in Outlook and do some basic mail tracing.

Once you received an email, you would know the sender’s name and domain (For example, or….etc) easily. But it is not straightforward to know the IP address or the location (country) the email originated. Finding the originating IP (Sender’s IP) of particular mail will be helpful to find the location of the sender or the sending mail server. This can help in troubleshooting and finding the spammer details up to a certain level.

  • Probably you will be seeing several IPs in a mail header. It might be your receiving mail server, sending mail server and the sender’s computer/mobile device IP. It all depended on how the sender’s email application is configured or the default settings of the mail service.

While searing for ‘IP’ from the copied email headers, it returns the following result for me.

The originating IP is possibly your mail server IP which received this email. Since mine is in Office 365, it is one of the office 365 email server IPs.

Other Ways to Read an Email Header and Trace email IP

There are few famous providers that provide useful services to read mail headers in a readable format. We can use the GSuite Toolbox message header or MX Toolbox’s header analyzer. After checking both tools, I found that the MX toolbox gives more useful information about IP addresses with DNS names of the servers and email sender.

To trace further about the email IP address, we can look for more information from or find the IP location.

  • Visit and input the sender IP you gathered from the earlier step by reading the email header.

Look For Whois Information

It will provide lots of information about the IP address you received in the email. With this, we almost traced the possible details about the email sender’s IP as an end-user.

The Truth:

It is not that simple to investigate and trace the email sender by the IP address from the email header. Even the methods I mentioned have some limitations and they will not be accurate all the time. If someone really wants to trick/hack you, they can spoof the email headers and mask the IPs. Even they can relay on some authentic email servers to send spam emails which may look genuine.

You can try the combination of the above methods by available data from Microsoft Outlook or Office 365 web access.  I hope these steps are useful to trace the IP address of an email up to a certain level from your computer.
