Consider the following scenario:
[PS] C:\Program Files\Microsoft\Exchange Server\V14\scripts>.\StartDagServerMaintenance.ps1 Mailbox Server
The following objects are hosted by Mailbox Server, before attempting to move them off: `n(Database=<Mailbox Database>, Reason='Copy is critical for redundancy according to Red Alert script'))
Write-Error : The following objects are still hosted by Mailbox Server, even after attempting to move them off: `n(Database=Mailbox Database, Reason='Copy is critical for redundancy according to Red Alert script'))
At C:\Program Files\Microsoft\Exchange Server\V14\scripts\StartDagServerMaintenance.ps1:216 char:16
+ write-error <<<< ($StartDagServerMaintenance_LocalizedStrings.res_0014 -f ( PrintCriticalMailboxResourcesOutput($criticalMailboxResources)),$shortServerName) -erroraction:stop
+ CategoryInfo : NotSpecified: (:) [Write-Error], WriteErrorException
+ FullyQualifiedErrorId : Microsoft.PowerShell.Commands.WriteErrorException,Microsoft.PowerShell.Commands.WriteErrorCommand
