How to Delete A Default Mailbox Database from Exchange server 2016

This article will show you ways to delete a default mailbox database from Exchange Server 2016 which Involved a couple of extra steps compared to previous versions on Exchange Server.

Before I can delete the default database i want to maneuver the AuditLog, Monitoring, Arbitration, and every one other mailboxes otherwise Exchange won’t allow you to Delete the database.

To start the method I run the 4 cmdlet below to maneuver the system mailboxes.

Get-Mailbox -Database “mailbox database 177274789” -AuditLog | New-MoveRequest -TargetDatabase mbxdbaex56

Get-Mailbox -Database “mailbox database 177274789” -Monitoring | New-MoveRequest -TargetDatabase mbxdbaex56

Get-Mailbox -Database “mailbox database 177274789” -Arbitration | New-MoveRequest -TargetDatabase mbxdbaex56

Get-Mailbox -Database “mailbox database 177274789” -Archive | New-MoveRequest -TargetDatabase mbxdbaex56

Once my system mailboxes are moved, I move all other mailboxes using the PowerShell Command below:

Get-MailboxDatabase “mailbox database 177274789” | get-mailbox | New-MoveRequest -TargetDatabase mbxdbaex56

Presently You can evacuate the database:

Remove-MailboxDatabase “mailbox database 177274789”
