Title

Disable the ability for Office users to use the Internet Fax Feature. (Cat II impact)

Discussion

Excel 2007, PowerPoint 2007, and Word 2007 users can use the Internet Fax feature to send documents to fax recipients through an Internet fax service provider. If your organization has policies that govern the time, place, or manner in which faxes are sent, this feature could help users evade those policies. By default, 2007 Office users can use the Internet Fax feature.
