Before we sent the Vista machine off we backed up via the Migration Wizard and with MS Backup onto a portable drive. When the machine came back with a new HDD we installed vista and ran MIG. Some clown got the MIG process backwards and overwrote the data with the blank Vista profile.
Luckily we have a complete backup, files are back but nothing else is. The most important part is Outlook. Obviously just dropping the files into the profile is no good, what now?
