Remove-EOPProtectionPolicyRule

Exchange Online ExchangeOnlineManagement Remove-*

Remove rules for the built-in security features for all cloud mailboxes in preset security policies. The rules specify recipient conditions and exceptions for the protection, and also allow you to turn on and turn off the associated preset security policies. **Note**: Use this cmdlet to remove a rule only if you plan to immediately recreate the rule using the New-EOPProtectionPolicyRule cmdlet. The affected preset security policy can't function without a corresponding rule.
