Enable Safe Attachments

EmailHigh severityNeeds DefenderForOffice P1

Safe Attachments detonates inbound attachments in a sandbox before delivery. Without it, malicious documents reach users immediately, relying on the recipient's endpoint AV — which often runs minutes after the user has already opened the file.

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.
