I was looking at SkyDrive Groups and noticed the storage limitation.

Now it is really annoying that there is a limit of 1GB, but that is not my question. I wonder how this is even calculated. I mean I have my personal folders on SkyDrive that I can select to share with my group. Does that mean they stop counting on my storage or ... ?

So What is counted and what is not. Does it matter who added it or where it came from. Are emails counted too towards the storage limit or not.

Just trying to understand how it is even possible to separate the storage that I bought and paid for on my account and that of the group which by the looks of it is stored in the same place :-)

Looking forward to a good explanation.
