Trusted Locations

Trusted locations are a new concept in Office 2007. A trusted location is a folder on your computer or on your network that has been designated as containing only safe documents. Excel workbooks, add-ins, and other Office documents that are placed in a trusted location will not be subject to any security restrictions. The Trusted Locations category is shown in Figure 22-2.

The Trusted Locations list shows two types of trusted locations. User Locations are trusted locations that are either added by the user or trusted by default. All Office 2007 template and startup folders, as well as the Office library folder, are trusted locations by default. Additional trusted folders can be added by the user. Policy Locations are trusted locations that have been defined by the network administrator for all users.

You can add new trusted locations using the Add New Location button. This button displays the dialog shown in Figure 22-3.

The Browse button is used to select a folder to trust. You can choose to trust all subfolders of the selected folder by placing a check mark in the Subfolders of this location Are Also Trusted checkbox. You can also add a description to the trusted location that will be displayed when this location is selected in the Trusted Locations list.

You cannot trust the root folder (for example, C:\) of any disk on your computer. By default, you cannot designate a network folder as a trusted location. If you want to trust a network folder, you must place a check mark in the Allow Trusted Locations on My Network checkbox shown at the bottom of Figure 22-2.

Selecting a location from the Trusted Locations list and clicking the Remove button will remove that folder from the list and prevent it from being a trusted location. Selecting a location from the Trusted Locations list and clicking the Modify button will redisplay the dialog shown in Figure 22-3 and allow you to make modifications to the selected location. These two buttons are disabled if no location is currently selected in the Trusted Locations list.

You can disable the trusted locations feature entirely by placing a check mark in the Disable All Trusted Locations checkbox shown at the bottom of Figure 22-2. If this option is selected, no folders of any type will be implicitly trusted, and only documents from trusted publishers will bypass security settings.
