Returning to the default behavior of BlackBerry devices and the BlackBerry Desktop Software
To restore the default behavior of a feature on BlackBerry® devices or in the BlackBerry® Desktop Software, you can change the IT policy rule value to Default, if that option is available, or delete the value that you previously specified.
If you assign users to a new IT policy, you can delete the IT policy to return those users to the Default IT policy. The Default IT policy provides the default behavior for all of the features on the BlackBerry devices and in the BlackBerry Desktop Software. The BlackBerry® Enterprise Server reassigns the users to the Default IT policy automatically and resends the Default IT policy to the BlackBerry devices.
