The BlackBerry® Enterprise Server Express includes a default IT policy. When you install the BlackBerry Enterprise Server Express, the IT policy rules in the default IT policy do not contain any values. If you do not specify a value for an IT policy rule, the default value is used. You can configure and apply the default IT policy to user accounts, or you can create new IT policies and assign the new IT policies to user accounts to control the BlackBerry devices in your organization's environment.
