Mail servers for outlook.de
outlook.de publishes 1 MX record. Senders deliver to the lowest-priority host first, eur.olc.protection.outlook.com, and fall back down the list if it does not answer.
Who runs the mail
The hosts match the pattern of Microsoft 365. Microsoft 365 (Exchange Online Protection) hosts the mail. Tenants are frequently configured to accept every address at the domain, so mailbox checks answer catch-all more often here than on other providers, and a risky verdict means the mailbox could not be disproved rather than that it is bad.
What this means for verification
An address at outlook.de passes the free checks (syntax, MX, lists), so the API goes on to the mailbox-level SMTP handshake, which ends before any message is sent. The result is deliverable, risky, or undeliverable with a reason field that names the evidence.
