Start Exchange Management Shell and type the command to display mailboxes in the whole forest and not just the domain you are logged into:
[PS] C:Windowssystem32>$AdminSessionADSettings.ViewEntireForest=$True
[PS] C:Windowssystem32>Get-MailboxDatabase -Server nbc-d-mbx02
Name Server Recovery ReplicationType
—- —— ——– —————
Database15 NBC-D-MBX02 False None
[PS] C:Windowssystem32>Get-MailboxDatabase “nbc-d-mbx02Database15” | Get-Mailbox
Now that you have the list of all mailboxes in the exchange database, move it to a different server
To work around the Arbitration mailbox issue, let’s find out the list of all Arbitration mailboxes
[PS] C:Windowssystem32>Get-Mailbox -Arbitration |ft Name, Servername
Name ServerName
—- ———-
SystemMailbox{1f05a927-0695-4348-bb62-d2369dcb23d5} nbc-d-mbx01
FederatedEmail.4c1f4d8b-8179-4148-93bf-00a95fa1e042 nbc-d-mbx01
SystemMailbox{e0dc1c29-89c3-4034-b678-e6c29d823ed9} nbc-d-mbx02
SystemMailbox{bb558c35-97f1-4cb9-8ff7-d53741dc928c} nbc-d-mbx02
Migration.8f3e7716-2011-43e4-96b1-aba62d229136 nbc-d-mbx02
Now will disable all of those since I do not have a different server to move them to.
[PS] C:Windowssystem32>Disable-Mailbox “SystemMailbox{e0dc1c29-89c3-4034-b678-e6c29d823ed9}” -Arbitration -DisableLastArbitrationMailboxAllowed

If the mailbox has an archive or remote archive, the archive will also be marked for removal. In the case of remote archives, this action is permanent. You can’t reconnect this user to the remote archive again.
