New-RetentionCompliancePolicy

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".

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.

The RestrictiveRetention parameter specifies whether Preservation Lock is enabled for the policy. Valid values are:

• $true: Preservation Lock is enabled for the policy. No one -- including an administrator -- can turn off the policy or make it less restrictive.
• $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 ways 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 retention policy, 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.
