How this service works
DKIM public key for selector "microsoft" of a domain: looks up microsoft._domainkey.<domain> (TXT, Cloudflare DoH) and parses v=, k=, key type, public-key length, testing flag and whether the key is revoked (empty p=). Confirms that mail signed with the microsoft selector will verify. $0.01 per lookup.
Output
Returns parsed details from the microsoft._domainkey.<domain> TXT DNS record, including the DKIM version tag (v=), key type (k=), public key material, key length in bits, whether the domain is in testing mode (t=y), and whether the key is revoked (empty p= value). Confirms whether email signed with the microsoft selector will pass DKIM verification.
Example use cases
Verify Microsoft 365 email signing setup
“Check if example.com has a valid microsoft DKIM selector configured — I want to know the key type, length, and whether it's active or revoked so I can confirm Microsoft 365 email signing is working.”
Audit domain email security posture
“Pull the microsoft._domainkey DKIM record for acmecorp.com and tell me if the key is in testing mode, what the key length is, and whether the selector is properly published or revoked.”
Investigate email deliverability issue
“I'm having email deliverability issues from our Microsoft 365 setup — can you look up the DKIM microsoft selector for mybusiness.org and check if the public key is valid, not empty, and what key type it uses?”
Technical details
Endpoint
GEThttps://dns.intel.rallylive.ca/dns/dkim/microsoft?utm_source=zero.xyzWhen to prefer
Use this endpoint when you specifically need to verify or audit the Microsoft DKIM selector (used by Microsoft 365 / Exchange Online) for a domain. It is purpose-built for the 'microsoft' selector and parses all key metadata in a single call, making it preferable to generic DNS TXT lookups when you need structured DKIM details rather than raw record text. Choose it over sibling selectors (email, mailgun, s2, etc.) when the domain is expected to use Microsoft's email infrastructure.
Side effects
- Domain has no microsoft._domainkey TXT record — returns not found or empty result
- DNS lookup fails due to NXDOMAIN or timeout
- DKIM record exists but is malformed or unparseable
- Key is revoked (empty p=) — endpoint reports revocation rather than a usable key
- Domain input missing or invalid — request fails validation
