Set-ATPBuiltInProtectionRule

This cmdlet is available only in the cloud-based service.

Use the Set-ATPBuiltInProtectionRule cmdlet to modify the rule for the Built-in protection preset security policy that effectively provides default policies for Safe Links and Safe Attachments in Microsoft Defender for Office 365. The rule specifies exceptions to the policy.

For information about the parameter sets in the Syntax section below, see Exchange cmdlet syntax.

Description

For more information about preset security policies in PowerShell, see Preset security policies in Exchange Online PowerShell.

Important

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 article lists all parameters for the cmdlet, you might not have access to some parameters if they aren't 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

Set-ATPBuiltInProtectionRule -Identity "ATP Built-In Protection Rule" -ExceptIfSentToMemberOf "Test Group1","Test Group2"

This example provides exceptions to the Built-in protection preset security policy for members of the specified groups.

Example 2

Set-ATPBuiltInProtectionRule -Identity "ATP Built-In Protection Rule" -ExceptIfRecipientDomainIs (Get-AcceptedDomain).Name

This example provides exceptions to the Built-in protection preset security policy for recipients in all accepted domains. To see all of your accepted domains, run the following command: Get-AcceptedDomain | Format-List Name,DomainName.

Example 3

Set-ATPBuiltInProtectionRule -Identity "ATP Built-In Protection Rule" -ExceptIfRecipientDomainIs $null -ExceptIfSentTo $null -ExceptIfSentToMemberOf $null

This example remove all exceptions from the Built-in protection preset security policy.

Parameters

-Comments

Applicable: Exchange Online

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.

Parameter properties

Type:String
Default value:None
Supports wildcards:False
DontShow:False

Parameter sets

(All)
Position:Named
Mandatory:False
Value from pipeline:False
Value from pipeline by property name:False
Value from remaining arguments:False

-Confirm

Applicable: Exchange Online

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.
