System Attendant Mailbox cannot be accessed

Good morning,

I am just now done migrating my users from Exchange 200z to Exchange 2013.  Everything is fine, but now I am unable to remove my migration batch.  The error I get is this:

The Mailbox /o=First Organization/ou=Exchange Administrative Group(FYDIBOHF23SPDLT)/cn=Configuration/cn=Servers/cn=MX/cn=Microsoft System Attendant could not be opened.
    + CategoryInfo          : NotSpecified: (:) [Get-MigrationBatch], StorageTransientException
    + FullyQualifiedErrorId : [Server=MX,RequestId=aaa63026-8015-4385-933a-b9d3d857122c,TimeStamp=11.12.2014 05:39:28]
    [FailureCategory=Cmdlet-StorageTransientException] CBB1763,Microsoft.Exchange.Management.Migration.GetMigrationBatch

If I ask for arbitation mailboxes they seem to be there...

Restart the System Attendant Service on all servers. Wait about 15 minutes then try again.
