Click start run mobsync
uncheck all locations in sync manager, then click the setup tab and uncheck all the locations under Logon/Logoff

Once this is done open a command prompt and type

reg add “hklm\SOFTWARE\Microsoft\Windows\CurrentVersion\netcache” /v FormatDatabase /t reg_dword /d 00000001
reg delete “hkcu\Software\Microsoft\Windows\CurrentVersion\netcache\shares” /f
reg add “hkcu\Software\Microsoft\Windows\CurrentVersion\NetCache\Shares” /ve
reg delete “hkcu\Software\Microsoft\Windows\CurrentVersion\netcache\AssignedOfflineFolders” /f
reg add “hkcu\Software\Microsoft\Windows\CurrentVersion\NetCache\AssignedOfflineFolders” /ve

Reboot your computer and offline files will start to rebuild, restart again for the redirected folders to rebuild.
