Hi team , i have one exchange 2007 100GB database.edb, but if i count of users mailbox totally comes to only 60GB and whilte space 5gb , i dont understand where rest of space occupying and how to reduce please help me Thanks Vino

The simple way to reduce the size of the database is to create another one or two and then move the users to those databases. With Exchange 2007 you can have up to 4 databases. Although 100gb isn't exactly large. Some discrepency between the mailbox sizes and the database is not unusual. Deleted Item retention is probably the main cause.

Hi, also because SCR enable configuration growing fast?or problem in SCR setting . i have problem in SCR setup only and other singal db working normal . Thanks vino

SCR uses the logs, not the database for its replication, therefore the use of SCR should have nothing to do with it. Simon.Simon Butler, Exchange MVP Blog | Exchange Resources
