Outlook Express Security - Disable access to Outlook Express and protect
Use Outlook Express Security to control access to Outlook Express and its databases. When it is active, Outlook Express becomes locked and no third-party programs can access its message base files and the address book. As a result, when you try to start Outlook Express, open the address book or access the files, a password will be asked to allow access. If an invalid password is entered, Outlook Express or Address Book will not be opened.
