Microsoft sends service-health incidents, security advisories, and license/billing notifications to addresses on file in the tenant. If these default to the original signup contact (often a personal email of a long-departed admin), important messages — including Microsoft's own breach notifications to your tenant — get lost.
A scan reports where your tenant stands on this check — pass, fail with a step-by-step fix, or not applicable if your licensing doesn’t include the feature. When Tenant Strike can’t read a setting with read-only access, it says unverified and gives you a one-command way to confirm it yourself — it never guesses.
