Just to give some feedback on this issue. The 2 users workstations that we were testing on, had an ""App Volume"" software associated with their profile. This gives them the use of Microsoft Access and another application named Monarch. If the App Volume service is running on the workstation, the synchronization causes a conflict and doesn't complete. When I tested on other user workstations, the Sage client synchronization completed successfully. Now their IT team have to research why the App Volume doesn't allow the sync process to complete.
