How this service works
TXT record of owa.<domain>: looks up the owa host under the domain you give (TXT 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> subdomain exists in DNS, along with any TXT records associated with it, the TTL value, and the DNS response code — all as answered by Cloudflare's 1.1.1.1 DNS over HTTPS resolver.
Example use cases
Verify Exchange OWA deployment for a domain
“Does microsoft.com have an owa subdomain set up? Check its TXT records and tell me if it exists and what the TTL is.”
Recon email infrastructure for a prospect
“I'm doing research on acmecorp.com — can you check if they have an owa host configured in DNS and what TXT records are on it?”
Confirm OWA presence before pen test engagement
“Before I start the engagement, check whether owa.targetdomain.com resolves and has any TXT records — I need to know if Exchange OWA is exposed.”
Technical details
Endpoint
GEThttps://dns.intel.rallylive.ca/dns/host/owa/txt?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you specifically need to check for the presence and TXT records of the owa subdomain (commonly used for Microsoft Outlook Web Access / Exchange) under a given domain, without enumerating other subdomains. Prefer it over general DNS TXT lookups when the target subdomain is specifically 'owa', and over full subdomain enumeration tools when you only need a targeted existence check for this well-known host.
Side effects
- Domain does not exist — NXDOMAIN response returned with no records
- owa subdomain exists but has no TXT records — empty record set with NOERROR
- Malformed or missing domain input — request rejected or invalid response
- Cloudflare DoH resolver temporarily unavailable — service error or timeout
- Rate limiting or payment failure — request not processed
