From observation to a useful check
- What was observed
- The DNS records and classifications in this snapshot.
- What it means
- MX describes inbound mail; SPF authorizes senders.
- What is unknown
- The actual sending IP, nested SPF dependencies, inbox placement and commercial relationships. MTA-STS, TLS-RPT and BIMI adoption are not measured.
- Next check
- Verify current DNS and test a real message: run an inbox placement test.

DNSSEC records are shown only when returned. An unset AD flag is not proof that a zone is unsigned. MTA-STS, TLS-RPT, BIMI and arbitrary DKIM selectors are not measured here; their absence cannot be inferred.
Recorded DNS history
This history starts with saved RR captures. Provider market-share charts are aggregate context, not this domain’s DNS history. Dates identify observations; no continuous validity between them is implied. Equivalent RR states are combined, ignoring response TTL and capture-time changes. Up to 30 distinct RR states and 60 dated captures are retained within a per-domain byte limit.

Where office.com stands
The same snapshot cut by zone, by list position and by how alive the published policies are.
- At this list position the top three mailbox providers hold 60.8% of domains (Google Workspace, Microsoft 365, Unknown / Other).
- Across the dataset 25.1% of DMARC records are inert — policy does nothing and no reports are collected.
How to interpret these observations
MX identifies the observed inbound mailbox or gateway. SPF includes identify services authorised to send for the domain. DMARC shows the published authentication policy. The dataset currently contains 1 populated signal groups for this page.
Observed deliverability context: based on the available observations, this page describes DNS configuration only. It does not represent a complete audit of office.com and does not prove that a particular message reaches the inbox or spam folder.
