I have a backup of Exchange 2003 that was from a crashed SBS 2003 server. The new server has been installed (SBS 2011) and i was able to export/import using PST files from each workstation. However, there is a public folder calendar and a couple of mailboxes from non-existent users that need to be retrieved from the backup.
What would be the best way to recover those items? As additional information, I do have access to another SBS 2003 server.
