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?
When I switch users mahcines I backup the .pst, located in
C:\Documents and Settings\userprofile\Local Settings\Application Data\Microsoft\Outlook
Then, on the new machine, I setup an Outlook account with the users email address, password, etc. Outlook will create a new .pst, which I overwrite with the old one.
Restart Outlook and you're good to go.
