| Outlook in the (security) zone |
| |
Outlook uses Internet Explorer's security zones to determine what actions HTML content in a message can perform. These security zones include settings that determine whether scripts can run, whether unsigned ActiveX controls can download, or whether certain other actions can occur.
Outlook defaults to the Restricted security zone. Assuming your system uses the default settings for the Restricted zone, this means that HTML messages in Outlook are rather limited. For example, VB script in a message won't execute when you view the message.
When processing messages, Outlook only uses its selected zone; it doesn't consider the settings for any others. For example, assume you've added several sites to the Restricted zone to identify ones that are potentially harmful and then switched Outlook to the Internet zone. Now when a message comes from a domain on the restricted list, Outlook takes no action other than displaying the message with whatever settings are configured in the Internet zone.
If you've configured Outlook to use the Restricted zone and want to view a particular message in the Internet zone (because it contains script code that you want to execute, for example), open the message and then choose View | View In Internet Zone. Outlook then switches zones for that one message. The View In Internet Zone command won't appear in the menu if you've configured Outlook to use the Internet zone by default. |
