Supported filter policy action used.

Why This Matters

Anti-malware and spam filter policies in Microsoft 365 must use supported actions to ensure consistent protection across your organization. Configuring an unsupported action could leave mail flow unprotected or cause filtering to fail silently, increasing the risk of malicious content reaching user inboxes.

What Aether365 Checks

Aether365 verifies that each anti-malware or spam filter policy in your Microsoft 365 tenant is using a supported action for both the policy type and the filtering context. This check appears in the Aether365 dashboard under the Microsoft 365 security checks section.
