domain anomalies

The domain anomalies tag focuses on Microsoft Teams’ External Domain Anomalies report and how administrators should interpret its signals. The report highlights unusual external collaboration, including domains generating many first-time contacts, and can support decisions to keep a domain open, place it on a named-domain allowlist, or block it after investigation. The tagged discussion stresses that an anomaly is not proof of phishing or compromise. It is a behavioral view rather than a content scanner, a verdict on messages, or a complete inventory of risky conversations, and legitimate partner rollouts can produce the same pattern.
