Si vous essayez de décommissioner un Exchange 2010
La solution la plus probable est qu’il reste les « Arbitration Mailboxes« , on à donc un message de ce genre.
The mailbox database ‘Mailbox Database **********′ cannot be deleted.
Mailbox Database **********
Failed
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 <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 -DisableLastArbitrationMailboxAllowed 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>.
Il va donc falloir vérifier qu’il sont encore sur le 2010 et les rapatrier sur le 2013 …
- Vérification de la présence sur l’ancienne DB
Get-Mailbox -Arbitration -Database "DB_NAME_2010"
- Move des Mailboxes sur la nouvelle DB
Get-Mailbox -Arbitration -Database « DB_NAME_2010 » | New-MoveRequest -TargetDatabase « DB_NAME_2013 »
- Si la commande n’affiche plus de Mailboxes, c’est migré !
Get-Mailbox -Arbitration -Database "DB_NAME_2010"
Il sera ainsi possible de continuer la désinstallation …
