Set-RetentionCompliancePolicy

This cmdlet is available only in Security & Compliance PowerShell. For more information, see Security & Compliance PowerShell.

Use the Set-RetentionCompliancePolicy cmdlet to modify existing retention policies in the Microsoft Purview compliance portal.

Note: Running this cmdlet causes a full synchronization across your organization, which is a significant operation. If you need to update multiple policies, wait until the policy distribution is successful before running the cmdlet again for the next policy. For information about the distribution status, see Get-RetentionCompliancePolicy.

For information about the parameter sets in the Syntax section below, see Exchange cmdlet syntax.

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.

Note: Don't use a piped Foreach-Object command when adding or removing scope locations: "Value1","Value2",..."ValueN" | Foreach-Object {Set-RetentionCompliancePolicy -Identity "Regulation 123 Compliance" -RemoveExchangeLocation $_}.

Examples

Example 1

Set-RetentionCompliancePolicy -Identity "Regulation 123 Compliance" -AddExchangeLocation "Kitty Petersen" -AddSharePointLocation "https://contoso.sharepoint.com/sites/teams/finance" -RemovePublicFolderLocation All -Comment "Added new counsel, 9/9/14"

This example makes the following changes to the existing retention policy named "Regulation 123 Compliance":

  • Adds the mailbox for the user named Kitty Petersen.
  • Adds the SharePoint Online site https://contoso.sharepoint.com/sites/teams/finance.
  • Removes public folders.
  • Updates the comment.

-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.

-RestrictiveRetention

The RestrictiveRetention parameter specifies whether Preservation Lock is enabled for a retention policy or retention label policy. Valid values are:

  • $false: Preservation Lock isn't enabled for the policy. This is the default value.

After a policy has been locked, no one can turn off or disable it, or remove content from the policy. And it's not possible to modify or delete content that's subject to the policy during the retention period. The only way that you can modify the retention policy are by adding content to it, or extending its duration. A locked policy can be increased or extended, but it can't be reduced, disabled, or turned off.

Therefore, before you lock a policy for retention, it's critical that you understand your organization's compliance requirements, and that you don't lock a policy until you are certain that it's what you need.
