The arbitration mailbox 'SystemMailbox{{e0dc1c29-89c3-4034-b678-e6c29d823ed9}}' for the organization '{0}' is located on a server that doesn't have Exchange Server 2010 SP1 installed. The arbitration mailbox  must be moved to an Exchange 2010 SP1 server before you can search for admin audit log entries using the Search-AdminAuditLog or New-AdminAuditLogSearch cmdlets. Until the arbitration mailbox is moved to an Exchange 2010 SP1 server, audit logs will be stored in the mailbox listed in the output of the Get-AdminAuditLogConfig cmdlet when it's run on a computer running Exchange Server 2010 RTM. Audit log entries in this mailbox can be viewed using Outlook Web App or another e-mail client.
