Thank you for your reply Eben. That was straightforward and easy to understand.
I am quite sure now though that many will not be using the SkyDrive Pro on Office 365 service because a 7GB storage capacity that cannot be increased is worse than using the consumer regular SkyDrive service where you can up that to 100GB if you wanted to by paying.
Quite funny that the consumer offering has more flexibility than that offered to companies.
