How can I defragment Exchange 2000/2003 Server databases?

Exchange databases run a defragmentation process once a day by default. This process rearranges mailbox store and public folder store data more efficiently, eliminating unused storage space. Exchange database online defragmentation occurs automatically as part of the database maintenance process. Online defragmenting is performed automatically at 2:00 AM every day by default. Online defragmentation makes additional database space available by detecting and removing database objects that are no longer being used. The defragmentation process provides more database space without actually changing the file size of the database.

Changing Store Limits in Exchange 2003 SP2

By default, the size limit of each database on a server running Exchange 2000 and Exchange Server 2003 Standard Edition is 16 GB (this limit is also enforced in SBS 2000/2003). Exchange Server 2003 Service Pack 2 (SP2) is supposed to remove this limit and thus allow for further DB size growth.

After installing Exchange Server 2003 Service Pack 2, the default size limit for each Exchange database is 18 GB, but can easily be configured to allow for database size limits of up to 75 GB per database.

Note: Exchange 2000 Standard Edition and SBS 2000 do not have this feature and continue to have the 16 GB limit enforced.
