I am a technical support analyst for a public transportation company. This past Friday, 8/13/10, our Exchange server may have been compromised, and our database became corrupt. Of course, the network engineer had nothing to back it up, not even to a replication server, so we've had to create new profiles for all of our employees, including exporting and importing .pst files and the like. Our employees use Outlook 2007 for now until a planned upgrade at the end of the year to 2010. Besides having to create new profiles, import and export files from old to new, is there a more efficient or effective way we could be restoring our employees information with minimal data loss? Any insight would be greatly appreciated, thank you in advance.
