Malware Filters

This report lists the malware filter policies configured in the selected tenant, each paired with the rule that decides who it applies to. It shows whether a policy is in force, which domains it covers, how the common attachment type filter is set, and where administrator notifications are sent.

Table Details

The properties returned are for the combination of the following Exchange PowerShell commands. For more information on the command please see the Microsoft documentation:

• Get-MalwareFilterPolicy

• Get-MalwareFilterRule

Every row is a policy. Rule Name, Priority, Recipient Domain Is, and State come from the rule paired with that policy, and everything else comes from the policy itself.

The built-in default policy shows no Rule Name, Priority, Recipient Domain Is, or State, and cannot be enabled or disabled from this page. Manage it from the Microsoft 365 Defender portal or with a CIPP standard instead.

Table Actions

Action	Description	Bulk Action Available
Enable Rule	Brings the policy into force so it starts applying to the recipients its rule covers. Greyed out where State is already Enabled.
Disable Rule	Stops the policy applying while keeping all of its settings, so it can be brought back later. Greyed out where State is already Disabled.
More Info	Opens the Extended Info flyout with the full details for the selected row.
