This is using MS Exchange 2010 with SP3. There are 3 Exchange servers holding mailbox and hub transport roles. These 3 exchange servers are in DAG. A mailbox database was found growing with size of nearly 600 GB. 200+ mailboxes were housed in it. However, we removed 40+ mailboxes, and we going to remove up to 60 mailboxes in 3 months' time. However, as expected, the db size not reduced.

I know that in order to reduce the size, we have to dismount the db, and then use microsoft tool - eseutil to "purge away"the white spaces. This method is called offline defrag and it may takes days to complete the operations.

Is there any alternative way to defrag (online or so) and reduce the db size without or with minimal downtime?

Thanks in advance.
