How this service works
CNAME record of autodiscover.<domain>: looks up the autodiscover 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 autodiscover without enumerating subdomains. $0.01 per lookup.
Output
Returns whether the autodiscover.<domain> CNAME record exists, the CNAME target value(s), and the TTL of the record as resolved via Cloudflare DNS over HTTPS.
Example use cases
Email Autodiscover DNS Audit
“Can you verify whether autodiscover.acmecorp.com has a CNAME record set up? I need to know if it exists and what it points to so I can troubleshoot Outlook autodiscover issues.”
Domain Onboarding Pre-flight Check
“Before we migrate email for clientdomain.org, check whether their autodiscover subdomain has a CNAME record and what the TTL is — I need to know if we'll have to wait for DNS propagation.”
Competitor Email Infrastructure Recon
“Look up the CNAME record for autodiscover.rivalcompany.com — I want to see if they've configured email autodiscover and which provider it points to.”
