Please make sure the public folder store is mounted and replicas exist of the offline address list folders. No offline address lists have been generated Outlook Errors: Replicas The first thing to check is the replicas for the Offline Address Book on the Exchange server itself. Follow the Instructions below. The main folder and each of its sub folders should be checked to ensure that there is at least one server listed.
