View antispam stamps in Outlook

The built-in antispam agents in Exchange Server apply diagnostic metadata, or stamps, as X-headers to messages as they enter your organization. For more information about these stamps, see Antispam stamps. You can use Microsoft Outlook to view the antispam X-header fields in messages to help you diagnose spam-related problems.

Use Outlook 2010 or later to view antispam stamps

  1. Open Outlook on a client computer, and in the Mail view, double-click a message to open it.

  2. In the Tags section of the Ribbon, click the Message Options icon to display the message Properties dialog box.

  3. In the Properties dialog box, in the Internet headers section, use the scroll bar to view the antispam X-headers. The header fields to look for are:

It can be easier for you to find these values by selecting all of the text in the Internet headers field (CTRL key + A), copying the text (CTRL key + C, or right-click and choose Copy), and pasting the text into Notepad.
