We are testing archiving and basically the small release notes mention that if you don't assign a COS to an archive account, it sets unlimited quota, disables spam/virus and hides in GAL.

I would like to have several archive COS (based on user's current COS) with the main difference between them being that retention policy.

I can then assign an archive COS when enabling a user to be archived. But how do I create this archive COS and adjust the settings as default and further refine them ?
