I wanted to make sure you all knew about this little bit of information, buried in the page and the FAQ about Exchange 2003 SP2:
Q. Did the storage limit change?
A. Based on feedback from customers like you and because of the evolution of e-mail usage, we are increasing the storage limit for Exchange Server 2003 Standard Edition with SP2 to 75 gigabyte (GB).
[Update later in the morning: Yes, this will apply to SBS 2003 once E2K3 Service Pack 2 is installed on the SBS box]
[Another update: The way the limit worked before was that you had 16gb for one private store and 16gb for one public store. The way the limit will work in SP2 is that you have 75gb for one private store and 75gb for one public store.]
