Troubleshooting Offline files
The local Offline files database does not work well when server folders are moved and this problem is common. The best approach is to re-initialize the offline files on the clients with problems. This functionality is build in but hidden. On the client hold down "control" and "Shift" at the same time before clicking the delete files button in the Offline files tab. This will remove all records of shares and files from the local machine in the cache.
