HTML Message Dangers

Because HTML messages can contain script and ActiveX controls, they are a potential source of virus attacks. To guard against and HTML viruses that make it past your anti-virus software, you can tell Outlook to display HTML messages as plain text. Because scripts and ActiveX controls are not activated until the HTML is displayed, this prevents them from doing harm.

Switching from Plain Text to HTML Display If you have set your options to read HTML messages as plain text, you can switch an individual open message to HTML display by clicking the Info bar and selecting Display as HTML.

To guard against malicious HTML messages:

1.	Select Trust Center from the Tools menu.
2.	Click E-mail Security.
3.	Under Read as Plain Text, select Read All Standard Mail in Plain Text (this means unsigned messages).
4.	If you want to include digitally signed messages, select Read All Digitally Signed Mail in Plain Text.
5.	Click OK.
