I have Journaling setup on Exchange 2007 and it has been working great with MXLogic Mail Archive. I just recently discovered it is journaling everything sent to the mailbox db, but not mail enabled public folders. I see where you can create a Journal Rule with the Hub Transport at the ORG level, but do I need Exchange 2007 Enterprise to do this or special licensing? There is a disclaimer about premium journaling and Exchange Enterprise CALs in order to do this. Any help or assistance anyone can provide is greatly appreciated. Thanks in advance.

Yes, Premium Journaling requires Enterprise CALs: http://technet.microsoft.com/en-us/library/aa998649(EXCHG.80).aspx
