[<CommonParameters>] Description
You need to add the antiphish rule to an existing policy by using the AntiPhishPolicy parameter. You create antiphish policies by using the New-AntiPhishPolicy cmdlet.
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 Common policy settings.
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-AntiPhishRule -Name "Research Department" -AntiPhishPolicy "Research Quarantine" -SentToMemberOf "Research Department"This example creates an antiphish rule named Research Department with the following settings:
- The rule is associated with the antiphish policy named Research Quarantine.
- The rule applies to members of the group named Research Department.
Parameters
-AntiPhishPolicy
The AntiPhishPolicy parameter specifies the antiphish policy that's associated with the antiphish rule.
You can use any value that uniquely identifies the policy. For example:
- Name
- Distinguished name (DN)
- GUID
You can't specify the default antiphish policy. And, you can't specify an antiphish policy that's already associated with another antiphish rule.

-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 |

-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. This is the default value.
- $false: The rule is disabled.
In the properties of the rule, the value of this parameter is visible in the State property.

| Required: | False |
| Accept pipeline input: | False |
| Accept wildcard characters: | False |
| Applies to: | Exchange Online, Exchange Online Protection |
-ExceptIfRecipientDomainIs
The ExceptIfRecipientDomainIs parameter specifies an exception that looks for recipients with email addresses in the specified domains. You can specify multiple domains separated by commas.
| Type: | Word[] |
| Position: | Named |
| Default value: | None |
| Required: | False |
| Accept pipeline input: | False |
| Accept wildcard characters: | False |
| Applies to: | Exchange Online, Exchange Online Protection |
-ExceptIfSentTo
The ExceptIfSentTo parameter specifies an exception that looks for recipients in messages. You can use any value that uniquely identifies the recipient. For example:
- Name
- Alias
- Distinguished name (DN)
- Canonical DN
- Email address
- GUID
You can enter multiple values separated by commas. If the values contain spaces or otherwise require quotation marks, use the following syntax: "Value1","Value2",..."ValueN".
| Type: | RecipientIdParameter[] |
| Position: | Named |
| Default value: | None |
| Required: | False |
| Accept pipeline input: | False |
| Accept wildcard characters: | False |
| Applies to: | Exchange Online, Exchange Online Protection |
-ExceptIfSentToMemberOf
The ExceptIfSentToMemberOf parameter specifies an exception that looks for messages sent to members of distribution groups, mail-enabled security groups, or sent to Microsoft 365 Groups. You can use any value that uniquely identifies the group. For example:
- Name
- Alias
- Distinguished name (DN)
- Canonical DN
- Email address
- GUID
You can enter multiple values separated by commas. If the values contain spaces or otherwise require quotation marks, use the following syntax: "Value1","Value2",..."ValueN".
If you remove the group after you create the rule, no exception is made for messages that are sent to members of the group.
| Type: | RecipientIdParameter[] |
| Position: | Named |
| Default value: | None |
| Required: | False |
| Accept pipeline input: | False |
| Accept wildcard characters: | False |
| Applies to: | Exchange Online, Exchange Online Protection |
-Name
The Name parameter specifies a unique name for the antiphish rule. If the value contains spaces, enclose the value in quotation marks (").
| Type: | String |
| Position: | 0 |
| Default value: | None |
| Required: | True |
| Accept pipeline input: | False |
| Accept wildcard characters: | False |
| Applies to: | Exchange Online, Exchange Online Protection |
-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.
Valid values and the default value for this parameter depend on the number of existing rules. For example, if there are 8 existing rules:
- Valid priority values for the existing 8 rules are from 0 through 7.
- Valid priority values for a new rule (the 9th rule) are from 0 through 8.
- The default value for a new rule (the 9th rule) is 8.
If you modify the priority value of a rule, the position of the rule in the list changes to match the priority value you specify. In other words, if you set the priority value of a rule to the same value as an existing rule, the priority value of the existing rule and all other lower priority rules after it is increased by 1.
| Type: | Int32 |

- Name
- Alias
- Distinguished name (DN)
- Canonical DN
- Email address
- GUID
You can enter multiple values separated by commas. If the values contain spaces or otherwise require quotation marks, use the following syntax: "Value1","Value2",..."ValueN".
