 ### Hierarchical namespace support
 
-Accounts that have a hierarchical namespace support immutability policies that are scoped to the container. However, you cannot rename or move a blob when the blob is in the immutable state and the account has a hierarchical namespace enabled. Both the blob name and the directory structure provide essential container-level data that cannot be modified once the immutable policy is in place.
+Immutable storage support for accounts with a hierarchical namespace is in preview. To enroll in the preview, see [this form](https://forms.office.com/Pages/ResponsePage.aspx?id=v4j5cvGGr0GRqy180BHbR9iuLyDgXDNIkMaAAVSMpJxUMVdIOUNDMlNESUlJRVNWOExJVUoxME1CMS4u).

+Keep in mind that you cannot rename or move a blob when the blob is in the immutable state and the account has a hierarchical namespace enabled. Both the blob name and the directory structure provide essential container-level data that cannot be modified once the immutable policy is in place.
+
+> [!IMPORTANT]
+> Immutable storage for Azure Blob Storage in accounts that have the hierarchical namespace feature enabled is currently in PREVIEW. See the [Supplemental Terms of Use for Microsoft Azure Previews](https://azure.microsoft.com/support/legal/preview-supplemental-terms/) for legal terms that apply to Azure features that are in beta, preview, or otherwise not yet released into general availability.
