How do i enable Google Storage purchase on a Google Apps domain?

Question

I can't seem to find how to enable this anywhere in the admin panel. Whenever I want to add paid storage for the Docs, it says it's not enabled on my domain.

How and where do I enable this?

Answer 1

So i found the answer.

You have to enable 'User Managed Storage' in the control panel. Under 'Organizations and Users' then 'Services'

That did the trick!
