When you open an Hypertext Markup Language (HTML) formatted e-mail message, embedded scripts may start without warning.
Active Scripting in the Internet security zone is enabled.
Scripting in Outlook is enabled by default. You can change this behavior by configuring Outlook to use the Restricted sites zone for security and customizing the Restricted sites zone to turn off Active Scripting.

CAUTION: Changing security zone settings can expose your computer to potentially damaging code. Use caution when you change these settings.

If you view the message in either AutoPreview or the Preview pane and there is script in the e-mail message, the script is not run. An S button appears on the right of the Preview pane header. When you click S, you receive a warning message even though you did not open the message or run any code. When you open the message, the script runs unless you perform the steps in the "More Information" section of this article.
