Group policy

Within the zip-file, there is a folder "admx" which contains the GPO template.

Copy admx-file and subdirectory "en" to: %systemroot%\PolicyDefinitions

Afterwards create a new policy (gpmc.msc). The settings are located at: User Configuration \ Policies \ Administrative Templates \ Outlookbackup addin settings

After configuring the settings, assign the policy file to an organisation unit (policy is user level).
