Verify a Outlook email address
Free, instant check for outlook.com, hotmail.com, live.com, msn.com addresses — syntax, DNS, typo and risk analysis from a real delivery engine.
What to know about validating Outlook addresses
- Microsoft consolidated Hotmail, Live and MSN under one mail system — all four domains behave identically for validation purposes.
- Microsoft 365 tenants often enable catch-all or quarantine rules, so a definitive per-mailbox answer needs more than DNS.
- hotmial.com and outlok.com are frequent typos the checker corrects.
