A configuration manager state cannot be set to OFF is one or more subscription still exist. The server still has a record of one or more subscriptions to its profiles.
Server operation continues. The command is not processed.
Use the QUERY SUBSCRIBERS command to determine which subscriptions still exist. The DELETE SUBSCRIBER command can be used to remove the record of these subscriptions. You may instead want to delete the actual subscription(s) on the managed server(s). When there are no more subscriptions recorded on the configuration manager, you must then delete all the profiles. Once the profiles have been deleted, you can reissue the command.
