Examples
Example 1
New-RetentionComplianceRule -Name InternalCompanyRule -Policy "Internal Company Policy" -RetentionDuration UnlimitedThis example creates a new case hold rule named InternalCompanyRule and adds it to the existing case hold policy named "Internal Company Policy". Content will be held indefinitely.
Example 2
New-RetentionComplianceRule -Name SeptOneYear -Policy "Internal Company Policy" -RetentionDuration 365 -RetentionComplianceAction KeepAndDelete -ExpirationDateOption ModificationAgeInDaysThis example creates a new retention rule named SeptOneYear and adds it to the existing retention policy named "Internal Company Policy". Content will be held for one year from the day content was last modified before it is deleted.
Parameters
-ApplyComplianceTag
The ApplyComplianceTag parameter specifies the label that's applied to email messages or documents by the rule (which affects how long the content is retained). A valid value for this parameter is the name of an existing label. If the value contains spaces, enclose the value in quotation marks.
You view and create labels by using the Get-ComplianceTag and New-ComplianceTag cmdlets.
You can't use this parameter with the Name or PublishComplianceTag parameters.
You can't use this parameter for Teams retention rules.
| Type: | String |
| Position: | Named |
| Default value: | None |
| Required: | True |
| Accept pipeline input: | False |
| Accept wildcard characters: | False |
| Applies to: | Security & Compliance |
-Comment
The Comment parameter specifies an optional comment. If you specify a value that contains spaces, enclose the value in quotation marks ("), for example: "This is an admin note".
| Type: | String |
| Position: | Named |
| Default value: | None |
| Required: | False |
| Accept pipeline input: | False |
| Accept wildcard characters: | False |
| Applies to: | Security & Compliance |
-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.
| Type: | SwitchParameter |
| Aliases: | cf |
| Position: | Named |
| Default value: | None |
| Required: | False |
| Accept pipeline input: | False |
| Accept wildcard characters: | False |
| Applies to: | Security & Compliance |
-ContentContainsSensitiveInformation
The ContentContainsSensitiveInformation parameter specifies a condition for the rule that's based on a sensitive information type match in content. The rule is applied to content that contains the specified sensitive information type.
This parameter uses the basic syntax @(@{Name="SensitiveInformationType1";[minCount="Value"],@{Name="SensitiveInformationType2";[minCount="Value"],...). For example, @(@{Name="U.S. Social Security Number (SSN)"; minCount="2"},@{Name="Credit Card Number"}).
Use the Get-DLPSensitiveInformationType cmdlet to list the sensitive information types for your organization. For more information on sensitive information types, see What the sensitive information types in Exchange look for.
You can use this parameter with the ApplyComplianceTag parameter.
You can't use this parameter for Teams retention rules.

-ExcludedItemClasses
The ExcludedItemClasses parameter specifies the types of messages to exclude from the rule. You can use this parameter only to exclude items from a hold policy, which excludes the specified item class from being held. Using this parameter won't exclude items from deletion policies. Typically, you use this parameter to exclude voicemail messages, IM conversations, and other Skype for Business Online content from being held by a hold policy. Common Skype for Business values include:
- IPM.Note.Microsoft.Conversation
- IPM.Note.Microsoft.Conversation.Voice
- IPM.Note.Microsoft.Missed
- IPM.Note.Microsoft.Missed.Voice
- IPM.Note.Microsoft.Voicemail
- IPM.Note.Microsoft.VoiceMessage.UA
- IPM.Note.Microsoft.Voicemail.UM
- IPM.Note.Microsoft.Voicemail.UM.CA
Additionally, you can specify message classes for Exchange items and custom or third-party message classes. Note that the values you specify aren't validated, so the parameter accepts any text value.
You can specify multiple item class values by using the following syntax: "Value1","Value2",..."ValueN".
You can't use this parameter for Teams retention rules.
