Have a database where everything has been removed & moved to other databases but this database cannot be deleted. This database had 1 DAG copy which has been removed and the copy successfully deleted from the other DAG member. Remove-MailboxDatabase MyDatabase This mailbox database contains one or more mailboxes, mailbox plans, archive mailboxes, or arbitration mailboxes. To get a list of all mailboxes in this database, run the command Get-Mailbox -Database <Database ID>. To get a list of all mailbox plans in this database, run the command Get-MailboxPlan. To get a list of archive mailboxes in this database, run the command Get-Mailbox -Database <Database ID> -Archive. To get a list of all arbitration mailboxes in this database, run the command Get-Mailbox -Database <Database ID> -Arbitration. To disable a non-arbitration mailbox so that you can delete the mailbox database, run the command Disable-Mailbox <Mailbox ID>. To disable an archive mailbox so you can delete the mailbox database, run the command Disable-Mailbox <Mailbox ID> -Archive. Arbitration mailboxes should be moved to another server; to do this, run the command New-MoveRequest <parameters>. If this is the last server in the organization, run the command Disable-Mailbox <Mailbox ID> -Arbitration -DisaleLastArbitrationMailboxAllowed to disable the arbitration mailbox. Mailbox plans should be moved to another server; to do this, run the command Set-MailboxPlan <MailboxPlan ID> -Database <Database ID>. + CategoryInfo : InvalidOperation: (MyDatabase:DatabaseIdParameter) [Remove-MailboxDatabase], AssociatedUse rMailboxExistException + FullyQualifiedErrorId : 6B234404,Microsoft.Exchange.Management.SystemConfigurationTasks.RemoveMailboxDatabase Ran these commands: Get-Mailbox -Database MyDatabase (no results) Get-MailboxPlan (cmdlet does not exist, we are not running in /hosting mode) Get-Mailbox -Archive -Datbase MyDatabase (no results) Get-Mailbox -Arbitration -Database MyDatabase (no results) Get-MoveRequest (no results) How can database MyDatabase be removed?

Hi 1. Run following command for permanently purges all soft-deleted mailboxes from mailbox database Get-MailboxStatistics -Database "XX" | where {$_.DisconnectReason -eq "SoftDeleted"} | foreach {Remove-StoreMailbox -Database $_.database -Identity $_.mailboxguid -MailboxState SoftDeleted} Purge all mailbox and run Remove-MailboxDatabase cmdlet again 2. Clean-MailboxDatabase -Identity "XX" http://technet.microsoft.com/en-us/library/bb124076.aspx 3.If above suggestion doesnt work, you can remove database through ADSI.

I did not realize Get-MailboxStatistics -Database "XX" would show other mailboxes in the db than what Get-Mailbox did. I saw several mailboxes that had been moved to other databases. Our environment is set to not delete until a backup so I purged these several mailboxes then was able to Remove-MailboxDatabase MyDatabase successfully. Thank you!
