How this service works
Requires an unauthenticated caller-owned baseline; returns real current NS/MX records, added/removed sets and tri-state target-provider transition. Current DNS comes from one bounded native recursive-resolver query; existing Dossier provides context. Resolver caching may apply; no account ownership or global migration-completion claim. Existing provider patterns are reused without new invented attribution. At most50records,domain253chars,9sbudget; DNSsubquery2s/oneattempt. Unknown provider remai
Output
Returns a structured payload including WHOIS registration data, full DNS record set, MX records with priority and exchange hostnames, mail policy details (SPF/DKIM/DMARC indicators), TLS certificate metadata, discovered subdomains, and a specific assessment of whether the domain routes mail through Microsoft 365.
Example use cases
Vendor email infrastructure audit
“I need to verify that acmecorp.com is actually using Microsoft 365 for email — check their MX records and tell me if any look misconfigured or unexpected.”
MX change drift detection
“We recorded that example.com had MX records pointing to outlook.com with priority 0 on 2024-11-01 — can you compare that baseline against what's live now and flag any changes?”
Security reconnaissance on target domain
“Do a full domain intel sweep on targetbrand.io — I want WHOIS, all DNS records, TLS cert details, subdomains, and especially whether their mail is going through Microsoft 365.”

Endpoint
POSThttps://dns.halowerk.com/domain/articles/mx-microsoft-365?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a no-signup, pay-per-call domain intelligence lookup that specifically highlights Microsoft 365 mail routing, with the added benefit of bundled WHOIS, DNS, TLS, and subdomain data in a single call. Ideal for agents performing one-off domain audits, security recon, or mail configuration validation without committing to a subscription API key.
Side effects
- Domain not found or unresolvable — returns empty or error response
- Invalid domain string exceeding 253 characters — schema validation error
- Baseline object malformed or missing required fields (domain, observed_at, records) — 400 validation error
- Payment not processed via x402 — 402 Payment Required response
- Rate limiting or upstream DNS resolver timeout — transient 5xx error
- Domain exists but has no MX records configured — returns empty MX array
