New-ATPProtectionPolicyRule
This cmdlet is available only in the cloud-based service.
Use the New-ATPProtectionPolicyRule cmdlet to create rules for Microsoft Defender for Office 365 protections 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: Unless you manually removed a rule using the Remove-ATPProtectionPolicyRule cmdlet, we don't recommend using this cmdlet to create rules. To create the rule, you need to specify the existing individual security policies that are associated with the preset security policy. We never recommend creating these required individual security policies manually. Turning on the preset security policy for the first time in the Microsoft Defender portal automatically creates the required individual security policies, but also creates the associated rules using this cmdlet. So, if the rules already exist, you don't need to use this cmdlet to create them.
For information about the parameter sets in the Syntax section below, see Exchange cmdlet syntax.

For more information about preset security policies in PowerShell, see Preset security policies in Exchange Online PowerShell.
Important
Different types of recipient conditions use AND logic (the recipient must satisfy all specified conditions). Different types of recipient exceptions use OR logic (the recipient must satisfy any of the specified exceptions). For more information, see Profiles in preset security policies.
You need to be assigned permissions before you can run this cmdlet. Although this topic lists all parameters for the cmdlet, you may not have access to some parameters if they're not included in the permissions assigned to you. To find the permissions required to run any cmdlet or parameter in your organization, see Find the permissions required to run any Exchange cmdlet.
Examples
Example 1
New-ATPProtectionPolicyRule -Name "Standard Preset Security Policy" -SafeAttachmentPolicy "Standard Preset Security Policy1622650008019" -SafeLinksRule "Standard Preset Security Policy1622650008534" Priority 1This example creates the rule for the Standard preset security policy. No restrictions are placed on who the Defender for Office 365 protections apply to. If the rule already exists, the command will fail.
Parameters
-Comments
The Comments parameter specifies informative comments for the rule, such as what the rule is used for or how it has changed over time. The length of the comment can't exceed 1024 characters.
| Type: | String |
| Position: | Named |
| Default value: | None |
| Required: | False |
| Accept pipeline input: | False |
| Accept wildcard characters: | False |
| Applies to: | Exchange Online |
-Confirm
The Confirm switch specifies whether to show or hide the confirmation prompt. How this switch affects the cmdlet depends on if the cmdlet requires confirmation before proceeding.
- Destructive cmdlets (for example, Remove-* cmdlets) have a built-in pause that forces you to acknowledge the command before proceeding. For these cmdlets, you can skip the confirmation prompt by using this exact syntax: -Confirm:$false.
- Most other cmdlets (for example, New-* and Set-* cmdlets) don't have a built-in pause. For these cmdlets, specifying the Confirm switch without a value introduces a pause that forces you acknowledge the command before proceeding.

-Enabled
The Enabled parameter specifies whether the rule is enabled. Valid values are:
- $true: The rule is enabled. The State value of the rule is Enabled. This is the default value.
- $false: The rule is disabled. The State value of the rule is Disabled.
After you create the rule, you turn on or turn off the preset security policy using one of the following commands:
- Turn off: Disable-ATPProtectionPolicyRule and Disable-EOPProtectionPolicyRule.
- Turn on: Enable-ATPProtectionPolicyRule and Enable-EOPProtectionPolicyRule.

-Name
The Name parameter specifies a unique name for the rule. The maximum length is 64 characters.
By default, the rules are named Standard Preset Security Policy or Strict Preset Security Policy. Since you don't need to create rules other than those used by the Standard preset security policy or the Strict preset security policy, we highly recommend that you use the default rule names for clarity and consistency.

-Priority
The Priority parameter specifies a priority value for the rule that determines the order of rule processing. A lower integer value indicates a higher priority, the value 0 is the highest priority, and rules can't have the same priority value.
The default value for the rule that's associated with the Strict preset security policy is 0, and the default value for the rule that's associated with the Standard preset security policy is 1.
When you create the policy, you must use the default value.
