ℹ️ What Is WHOIS?

WHOIS is a public database that stores domain registration records. Every registered domain has a WHOIS entry containing the registrar, creation date, expiry date, and nameserver configuration.

For outlook.office365.com, the WHOIS record shows who registered the domain and when. Many registrars offer privacy protection that masks the registrant's personal details, but the technical data (nameservers, dates, status codes) remains visible.
