How to move arbitration mailboxes

1
Get-Mailbox -Arbitration -Database “Mailbox Database SOURCE” | New-MoveRequest -TargetDatabase “Mailbox Database DESTINATION”

Deleting a database with arbitration mailboxes

When deleting a database, if you have the following message:

1
Error: 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 . 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 -Archive. To get a list of all arbitration mailboxes in this database, run the command Get-Mailbox -Database -Arbitration. To disable a non-arbitration mailbox so that you can delete the mailbox database, run the command Disable-Mailbox . To disable an archive mailbox so you can delete the mailbox database, run the command Disable-Mailbox -Archive. Arbitration mailboxes should be moved to another server; to do this, run the command New-MoveRequest . If this is the last server in the organization, run the command Disable-Mailbox -Arbitration -DisableLastArbitrationMailboxAllowed to disable the arbitration mailbox. Mailbox plans should be moved to another server; to do this, run the command Set-MailboxPlan -Database .

It will mean that arbitration mailboxes are still on this database.

We will move the arbitration mailboxes to another database, as seen previously with the command:

1
Get-Mailbox -Arbitration -Database “Mailbox Database SOURCE” | New-MoveRequest -TargetDatabase “Mailbox Database DESTINATION”
