Run cleanup agent in Exchange 2007 is Clean-MailboxDatabase cmdlet
Did ”Run cleanup agent” vanish in Exchange 2007?
It’s still there. 
Run this cmdlet from powershell “Clean-MailboxDatabase “name of the database”.
We use this normally after disbaling a user and when the user dont appear with the “Disconnected Users” section in EMC.

Finally, I found what I was looking for… I think MS need to document these stuffs properly… I disabled a user and was lost for a long time..
God bless you mate, and thanks from the deep of my heart, thank you. Best regards.

Hi,
Will that command (Clean-MailboxDatabase) also clean the Exchange mailbox corrupted items or deleted item as well ?

Nope…. it will only do a cleanup on the DB to update the list of actual user’s residing on it…
