Hi
I created a new database and moved all the user mailbox's plus discovery mailbox;s over and all went well, i then unmounted and deleted the old database in ECP and stopped all the exchange services and deleted the old database files and folders from the C:, i noticed i was still getting some errors with windows backup and after looking around i notice for some reason under program files/microsoft/exchange server/v15/mailbox the old db folder appears with the sub folders 'indexmeta', 'journal' and 'ms', it seems that the last trace of the old databases is still being used because the date is always todays date! everytime i delete these foldersers they come back!!
I think this is the reason why the windows backup is failing with 'this application will not be available from this backup'
any help would be appreciated!
