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 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

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

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.
