You can view the Spam Score of any email you receive by checking that email's message headers. To view an email's message header's in Outlook, use the following steps:
1) In Outlook, double-click on the email you would like to examine to open it in a new window.
2) In the new window, click the File menu.
3) Click the Properties button.
4) The email message headers will be located in a box labelled "Internet headers".
The score can be found on the line "X-Spam-Score". This line is usually located around the middle of the header contents or lower, depending upon the route the email took from the sender to your mailbox.
