Ensure communication with unmanaged Teams users is disabled
Why This Matters
Allowing your Teams users to communicate with unmanaged external users can expose your organization to data leakage, phishing attacks, and unauthorized information sharing. Without proper controls, external parties can contact employees directly, bypassing your security boundaries and compliance policies. Disabling this capability reduces the risk of social engineering and ensures all external collaboration is governed by your tenant's security settings.
