I have a customer running Windows 7 Pro that wanted the ability to search files on the network drive so I enabled Offline Files. The search worked for a few days, however now the end user is complaining that some files that she updated are missing data. Files she know she made changes to. I poked around and noticed the mapped drive where the Offline Files is located shows Offline File System: CSC-CACHE. I have visited the Sync Center and it shows errors. When I try to "fix" the sync error "Keep both files" it generates a new error stating the files cannot be found. I don't want to rebuild the offline files as I don't want to loose the newer files on her local computer. Any suggestions?
