    Just what I needed. I found this blog, after 3 hrs of struggle updating my mail servers with CU2 for exchange server 2013 We deleted folder hierarchies, after migrating from Exchange 2007 , thinking we do not need this Object anymore. Do you know why Exchange server 2013, looking for this Object ? John

    I believe that Exchange 2010 deletes this object when you remove the last public folder database from an organization. (Even if public folders have actually been migrated to Exchange 2013.) Or it happens during the uninstall of Exchange 2010.
