Increase database size limit to 75GB in Exchange

When I checked the SBS Premium 2003 then it was mentioning the database size limit which was not 75gb for Exchange. I testerd the database and it maxed out at only 16gb. I cannot see a way to configure Exchange to increase the database size to 75gb like it was mentioned. Can anyone please help me to achieve it? Thanks.

Prior to Microsoft Exchange Server 2003 Service Pack 2 (SP2), there was no method to configure database size limits for Exchange Server 2003. Exchange Server 2003 SP2 introduces the following new features, that you can find out in this link - http://technet.microsoft.com/en-us/l...78ab7c09c.aspx
