Add Resource calendars for all users.

Hi,

We are moving away from our old Public Folder shared calendars to Resource Calendars in Exchange 2010, clients are mostly Outlook 2010 as well.

Is there a way via GPO, script or anything that will allow me to add the new Resource Calendars automatically to all users Outlook Calendars? I'd really prefer doing it automatically for everyone over sending instructions for them to do it themselves.
