Disposable email database
Is outlook.com a disposable email?
Quick answer
outlook.com is operated by Outlook.com, a legitimate free email provider. Do not block — these users are real and represent a large fraction of healthy B2C and small-business signups.
About Outlook.com
Outlook.com is Microsoft's consumer webmail service, the successor to Hotmail. It is a legitimate free provider used by hundreds of millions of users for personal email.
What it’s typically used for
General personal email, particularly common with Windows users and longtime Hotmail account holders who migrated.
Other domains operated by Outlook.com
The same service runs additional alias domains. Block these alongside the main domain — otherwise users will simply switch to an alias to bypass your filter.
- hotmail.com
- live.com
- msn.com
Should you block outlook.com in your signup form?
Do not block @outlook.com signups. Treat the same as Gmail — score normally and watch for the same alias-style abuse tricks.
What you should do for Outlook.com signups: score them through your normal verification flow, watch for the same alias tricks (dot-variations,+tags), and keep the same disposable + IP checks running.
How to detect outlook.com in code
You don’t need to maintain a hand-rolled list. Vouchley returns a disposable flag (and the rest of the signup score) on every check:
curl -X POST https://api.vouchley.getrevlio.com/v1/verify \
-H "Authorization: Bearer vch_live_..." \
-H "Content-Type: application/json" \
-d '{
"email": "anyone@outlook.com",
"ip_address": "203.0.113.10"
}'

Vouchley keeps the disposable list current — including alias domains and new providers — so you never have to maintain it yourself.
