I have Win 98 and have tried to use MS Backup to back up to CD RW. Having selected the files which includes the Outlook express emails, the program in its report backs up everything with the exception two email .dbx files because it says they were busy. Outlook express was dormant at the time so it seems crazy. I have tried again and again. Out of 3568 files, 3566 were properly backed up. Does anyone know what is happening please?
