Click Tools>Options>Other>AutroArchive. Is autoarchiving enabled? If you,
you'll see the PST path there. You should also see a checkbox labeled "Show
archive folder in folder list". Check that and you should see the archive
folders in the Folder List view of the Navigation Pane. It's a simple matter
after that to open the archive folder containing the items you want to recover
and moving those items back to where you'd like them.
