Exchange PowerShell: Exporting mailbox folder AccessRights

Question

With PowerShell, I want to make an export of all the mailboxes in an Exchange environment of users in a specific OU where the level of AccessRights of the user "Default" on the folder level does not equal "None". For this I am using the following command:

$AllMailbox = Get-Mailbox -OrganizationalUnit "DNofOU" -ResultSize Unlimited 
$ResultData = foreach ($Mailbox in $AllMailbox) 
    {
        Get-MailboxFolderPermission $Mailbox | Where-Object {$_.User -Match "Default" -AND $_.AccessRights -NotMatch "None"} | Select-Object Identity,AccessRights,@{Name="Name"; Expression={$Mailbox.Name}}
    }  
$ResultData | Export-CSV -Path C:\temp\MailboxFolderPermissions.csv

However, when running this command I get the following error:

Cannot process argument transformation on parameter 'Identity'. Cannot convert the "DisplayNameOfMailbox" value of type "Deserialized.Microsoft.Exc hange.Data.Directory.Management.Mailbox" to type "Microsoft.Exchange.Configuration.Tasks.MailboxFolderIdParameter". + CategoryInfo : InvalidData: (:) [Get-MailboxFolderPermission], ParameterBindin...mationException + FullyQualifiedErrorId : ParameterArgumentTransformationError,Get-MailboxFolderPermission + PSComputerName : FQDNofExchangeServer

The environment is based on Exchange 2010 on a Windows Server 2008 R2 server with PowerShell version 2.0. It is also possible to execute this from a Windows Server 2012 R2 server with PowerShell version 4.0 when remote connecting to the Exchange server.

For me, it worked better to use the full Canonical name of the object. Like so:

$mailboxArray = Get-Mailbox -OrganizationalUnit "example.com/Accounts" -ResultSize Unlimited

I Wasn't sure if this for have found the answer or not yet, but wanted to provide my input on how you could possibly get all the mailboxes in an organizational Unit.
