Is there a way to use powershell to clear the "Recover Deleted Items" ? Or Make the "Recover Deleted Items" do not recover message any more?

Hi, To disable "Recover Deleted Items" for single user: Set-Mailbox User1 -RetainDeletedItemsFor 0.00:00:00 -RetainDeletedItemsUntilBackup $false -UseDatabaseRetentionDefaults $false To disable "Recover Deleted Items" for all user in a database Set-MailboxDatabase 'Database-01' -DeletedItemRetention 0.00:00:00 -RetainDeletedItemsUntilBackup $false Adam Bokiniec

Sorry for late update. Set Delete Items Retention is a helpful way to disable "Recover Deleted Items" ,Thanks Adam. But because I use powetshell to import PST file to Exchange , so set Delete Items Retention is not work for this kind of message. I found a way to clean up "recoverable items folder" : Search-Mailbox -Identity "Administrator" -SearchDumpsterOnly -TargetMailbox "Discovery Search Mailbox" -TargetFolder "Administrator-RecoverableItems" -DeleteContent But it just for Exchange 2010. So for Exchange 2007, how to clean uo "recoverable items folder" ?
