Outlook.com

What is Outlook.com?

Microsoft offers a personal email service alongside its work and school products.

Distinguish the service behind an address from the software someone uses to read mail. Avoid guessing employment from either one.

How should you handle Outlook.com signups?

Verify the address. Ask for organization details separately when your product actually needs them.

What you cannot infer

A personal Outlook address is not evidence of a fake signup, and the Outlook app can also hold accounts from other providers.
