Auto Accept Meetings Registry Entry ?

I am using auto accept meetings for resource scheduling and have found that I wish to invite users as resources so that the invitations are automatically accepted. This works well. I now wish to propagate the configuration to 150 desktops. I am trying to find a way to do this without visiting every desktop and individually configuring Outlook calendar preferences. I was hoping to find a registry entry to enable this but can not

Any Ideas
