Microsoft Outlook Express file extensions

Outlook Express is a different application from the Microsoft Office Outlook e-mail client. The two programs do not share a common codebase, but do share a common architectural philosophy. Outlook Express uses the Windows Address Book to store contact information and integrates tightly with it. On Windows XP, it also integrates with Windows Messenger.

In Windows Vista, Outlook Express is replaced with Windows Mail. Windows Live Mail has since been released as the successor to Outlook Express and Windows Mail.
