Question : Lotus client error document has been modified or corrupted since signed (data)

I'm trying to setup Lotus Notes client on another PC but get the following error "document has been modified or corrupted since signed (data)" for a specific user.  I've tried two separate PCs with the same result.  The client works fine on the old PC.  I've also tried copying the Data directory to ensure I'm not missing something but no change.

Answer : Lotus client error document has been modified or corrupted since signed (data)

Are you using the ID from the old machine or the Domino Directory?

Is the version of the notes client on the new machine different from the old?

Did you copy the notes.ini together with the old data folder?  Please check the folder  permissions on the copied data folder and make sure the user can access the data.
