Restrict OneDrive external sharing

OneDrive external sharing is controlled by the tenant-wide external sharing setting and, per Microsoft, can only be equal to or more restrictive than SharePoint — never more permissive. This informational check surfaces OneDrive's effective ceiling; the tenant-wide level itself is graded by the SharePoint external sharing check. (The OneDrive-specific override is not exposed by the read-only Graph API.)

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.
