My Outlook2003 & Outlook2007 won't launch. Help wanted.?

Question

I installed both Outlooks (2003 & 2007) on a desktop and on a nearby laptop. Each time I launch any of both on any of these PCs, both fail to launch (during the "Migration Account Settings", "Migrating Preferences" and "Importing User Data") and end up displaying:

C:\Documents and Settings\Administrator\Local Settings\Application Data\Microsoft\Outlook\Outlook.pst is not valid

I've tried installing from the default Administrator (Primary Admin) user account and from the created Administrator (Secondary Admin) account, from both I keep getting the message above. What's a ".pst" anyway?

Answer 1
