I have a laptop user that is trying to syncronise his offlines files. The laptop is set to perform this action during logoff and logon on the machine, but when he either starts up or shuts down he gets the error message - ' unable to merge offline changes on [path] the parameter is incorrect'. I have checked in the offline files folder and it appears to be empty. I have also checked in the users Event log and it is showing the following error - 'A portion of the offline files cache has become corrupt. Restart the computer to Clean up the cache'. The user has performed this action, but it has not resolved the issue, although the messages have stopped being written in the event log.
Does anyone have any ideas how I might resolve this issue?
