My Supervisor recently deleted public folders in preperation to migrate from 2007 to 2010 but had difficulties. Due to a folder called "Internet Newsgroups" not allowing deletion, He ended up deleting from Active Directory via ADSIEDIT, then in the Exchange console, deleted the storage group. Now we are unable to move the DB's to another node (CCR) as it says there is no Public Folder. In addition, all backups are now failing in MS Data Protection Manager. We do not have a backup of public folders and don't know what to do at this point. We am thinking we may need to migrate to 2010 sooner than later but we'd like to get this fixed if at all possible. Can anyone advise?
