Running offline defrag does not reduce database size.

I have an Exchange 5.5 server w/ Back Office 4.5 Standard and the Exchange database has hit the 16GB limit. I have run an offline defrag after having users clean up there mailboxes and the Information store started up fine, but Exchange is still showing sizes on mailboxes that are not true. Now the server is down again because of the store limits. Why did the offline line defrag not reduce and reclaim the space to relieve the 16GB limitation.

Thanks in advance,

Before running the offline defrag, did you shorten the number of days of the deleted items retention?  And then did you run an online defrag after the offline?

No and no. Exchange 5.5 is not my specialty. Where do I shorten the deleted items retension?

This should help you out, assuming the deleted items retention is enabled:
