NOTE: Applies to Microsoft Office Outlook 2003 and Microsoft Outlook 2002
To track what computer was used to open an e-mail message, use Outlook receipts. For this solution to work, the sender must first request a read receipt.
Receipts arrive in the Inbox as messages. A receipt indicates that someone opened the message. The Internet headers of the receipt provide more information. Technical details about a message are provided by Message headers.
Follow these steps to view the Internet header:
1. Open the read receipt message.
2. Select Options on the View menu.
You will see the headers in the Internet headers box
You will see multiple lines that say Received: from inside the headers. The last lines reveal the original computer from which the message was sent
Here's an example of this:
Received: from MikeTTigersPC ([192.168.0.27]) by smtpmail.litware.com with Microsoft SMTPSVC(6.0.3790.0);
Wed, 15 Dec 2006 13:38:49 -0800
This entry indicates that a computer with the name MikeTTigersPC with an assigned IP address of 192.168.0.27 was the computer on which the e-mail message was opened, and that it was the computer on which the read receipt was created at 1:38 P.M. (local time of the computer), on Wednesday, December 15, 2006.
NOTE: The address might not be a public IP address due to possible firewalls or private IP networks.
