Description
Office 365 functionality allows users to provide credentials for accessing Office 365 using either their Microsoft Account, or the user ID assigned by the organization. Access to Office 365 will not be permitted; only locally installed and configured Office 2013 installations will be used. Since the ability to sign into Office 365 will be disabled, this policy, which determines whether the Office First Run comes up on first application boot if not previously viewed, will also be disabled.
