Dear All used Exchange 2010 Server, so I move user from "Level1" mailbox store to "Level1DB" store but when I look back to physical edb file of Level1.edb size is not reduce, Please tell me how to defrag exchange 2010 edb file, I know only on exchange 2003 that used eseutil command but on exchange 2010 don't know, and on Exchange 2007 is same exchange 2010 or not?

You don't usually defrag Exchange 2007 or 2010 because of the multiple database support. Simply move all content to a new database and then drop the original. No risk, no downtime. I don't think I have ever defragged a Exchange 2007 or 2010 database and have no intention of doing so. Simon.Simon Butler, Exchange MVP Blog | Exchange Resources

Hi OniLu, Sembee gave some good suggestion. And Eseutil could be used all the versions of exchange. Regards! Gavin
