What is the Powershell command to configure a new Retention Policy in the Information Governance?

Thanks VasilMichev ,

but in the New-RetentionCompliancePolicy I have no option to define the Settings of the Policy, e.g. how many years I want the Retention to be in place.

It seems to me that this is defined in theNew-RetentionComplianceRule.

So what is defined in a new SCC Retention Policy UI seems to be a mix of New-RetentionCompliancePolicy and New-RetentionComplianceRule?

Am I correct here?

The New-RetentionComplianceRule would give me the Option of excluding IPM classes.

Thanks,

Franck
