Keep internet-facing servers on a supported version

External Attack SurfaceHigh severity

A version of Windows or Exchange Server that Microsoft has stopped supporting gets no fix for flaws found after that date. On a machine reachable from the internet, each new flaw stays open for good.

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.
