title: Azure WORM/ immutable retention lock on containers for legacy java SDK
body: <p>I wan to set up a <a href="https://docs.microsoft.com/en-us/azure/storage/blobs/storage-blob-immutability-policies-manage?tabs=azure-powershell" rel="nofollow noreferrer">immutable policy for blob storage</a> using the Java &quot;Legacy&quot; SDK (version 8.3), but I can't seem to find any documentation showing how to do this, or if it's even possible from the legacy version. The website shows how to do this from the portal, CLI and PowerShell, but I've yet to find any reference to the Java SDK. Am I missing some documentation somewhere?</p>
