[<CommonParameters>] Description
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
Set-ATPProtectionPolicyRule -Identity "Standard Preset Security Policy" -ExceptIfSentToMemberOf "Test Group1","Test Group2"This example provides exceptions to Defender for Office 365 protections in the Standard preset security policy for members of the specified groups.
Example 2
Set-ATPProtectionPolicyRule -Identity "Standard Preset Security Policy" -SentTo $null -ExceptIfSentTo $null -SentToMemberOf $null -ExceptIfSentToMemberOf $null -RecipientDomainIs $null -ExceptIfRecipientDomainIs $nullThis example removes all conditions and exceptions from the Standard preset security policy. No restrictions are placed on who the Defender for Office 365 protections apply to.
Parameters
-Comments
The Comments parameter specifies informative comments for the rule, such as what the rule is used for or how it has changed over time. The length of the comment can't exceed 1024 characters.
| Type: | String |
| Position: | Named |
| Default value: | None |
| Required: | False |
| Accept pipeline input: | False |
| Accept wildcard characters: | False |
| Applies to: | Exchange Online |
-Confirm
The Confirm switch specifies whether to show or hide the confirmation prompt. How this switch affects the cmdlet depends on if the cmdlet requires confirmation before proceeding.
- Destructive cmdlets (for example, Remove-* cmdlets) have a built-in pause that forces you to acknowledge the command before proceeding. For these cmdlets, you can skip the confirmation prompt by using this exact syntax: -Confirm:$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.
