Description

To use this cmdlet in Security & Compliance PowerShell, you need to be assigned permissions. For more information, see Permissions in the Microsoft Purview compliance portal.

Examples

Example 1

New-AppRetentionComplianceRule -Name RetUnlimited -Policy "Regulation 567 Compliance" -RetentionDuration Unlimited

This example creates a new retention rule named RetUnlimited and adds it to the retention policy named Regulation 567 Compliance.

Parameters

-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.

-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.

-ContentMatchQuery

The ContentMatchQuery parameter specifies a content search filter.

This parameter uses a text search string or a query that's formatted by using the Keyword Query Language (KQL). For more information, see Keyword Query Language (KQL) syntax reference and Keyword queries and search conditions for eDiscovery.

Position:Named
Default value:None
Required:False

-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".
