exchange display list of mailboxes allocated-size used-space

Asking about monitoring Exchange 2003 SBS, which I administrate.

Would like to see in one table a list of users-mailboxes displaying for each user the size-limit and the space used-up.

I can see a list showing the used-up space for each, in the “mailboxes” item. I can manually add “storage limits” but it only displays “within limits”, warning, etc, (not the actual limit) and I cannot keep that additional column for good.

Can I see a list of size limits (allocated space) for all?
Can I see both params in single list?
Can I generate a weekly report to be mailed to me?

Thanks,
Dany
