How this service works
CNAME record of owa.<domain>: looks up the owa host under the domain you give (CNAME via Cloudflare DoH) and reports whether it exists, its records and TTL. Quick existence check for common hosts like owa without enumerating subdomains. $0.01 per lookup.
Output
Returns whether the owa.<domain> CNAME record exists, the CNAME target record(s) it points to, and the TTL value of the record as resolved by Cloudflare DNS over HTTPS.
Example use cases
Verify OWA email portal presence
“Check whether microsoft.com has an owa subdomain configured with a CNAME record — does it exist and what does it point to?”
Corporate email infrastructure recon
“I'm auditing acmecorp.com's mail setup — can you tell me if their owa subdomain has a CNAME record and what its TTL is?”
Check competitor OWA deployment
“Does contoso.com use Outlook Web Access? Look up the CNAME for owa.contoso.com and tell me if it resolves to anything.”
Technical details
Endpoint
GEThttps://dns.intel.rallylive.ca/dns/host/owa/cname?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a fast, targeted check on whether a specific domain has an owa subdomain configured as a CNAME — ideal for email infrastructure auditing, OSINT reconnaissance on whether an organization uses Outlook Web Access, or verifying DNS setup without doing broad subdomain enumeration.
Side effects
- Domain does not have an owa subdomain — returns non-existence response
- Domain is invalid or malformed — may return DNS error
- Cloudflare DoH is temporarily unavailable — request may fail or time out
- Domain exists but owa host has an A record instead of CNAME — CNAME lookup returns empty
