You may experience a time when you move file servers due to restructuring or perhaps your old file server dies. You change the folder redirection paths to the new server, but offline files still tries to replicate from the old, non-existent server. To resolve this, you need to format the offline files database on your PC. This will remove the cached files database and old server references and fix your issue.

To format the offline file database open a command prompt and run the following command to add the necessary registry key to your PC and reboot.

REG ADD “HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\NetCache” /v FormatDatabase /t REG_DWORD /d 1 /f
