Error: Mailbox database contains one or more mailboxes arbitration mailboxes…….

Now if you are like me this will not make you happy and you will want to rename this DB something will make more sense to you, such as DB1, however you will realize you cannot change the name of the DB and this will drive you nuts each time you open EMC (-:, so let’s nuke it and create another one.

• Now just fallow simple steps , Open EMS ( Shell)

Figured out the name of the databases, you need to create least one more since you will move users from this DB into another one and delete is once there is no mailbox in the first database.

Get-Mailbox -Database

Get-Mailbox -Database db1 -Arbitration | ft -wrap -auto

New-MoveRequest -Identity "DiscoverySearchMailbox {D919BA05-46A6-415f-80AD-7E09334BB852}" -TargetDatabase DB2

***Pay attention little carrots and semi columns are going to make difference , so you have to use exactly same name on the New-MoveRequest CMDLET***

Get-Mailbox -Database db1 | ft -wrap –auto

Get-MoveRequest
