What's different between Outlook.com and Outlook?

Here's more info on the Outlook.com email service, the Outlook desktop app, and Outlook Express.

Outlook.com

Outlook.com is free web-based personal email service that helps you share, organize, and stay up to date like never before.

You can sign in to your Outlook.com email from your browser.

Outlook desktop app

The Outlook desktop app—for PCs and Macs—is part of the Office suite. It's the world’s most popular app for reading email, managing a calendar, and connecting to people. It works with both your personal email and your work email.

If you're running Windows 7 or Windows 8, you can get the latest version of Outlook by purchasing an Office 365 subscription or buying it as a standalone.

Outlook Express is no longer available or supported by Microsoft. It's a free desktop mail app that was included with pre-Windows 7 versions of Internet Explorer.

Windows Live Mail is a free email app similar to Outlook Express that helps you manage multiple email addresses, calendar info, and contacts.
