Azure Portal

In order to use Immutability with Azure Blob Storage, you must setup Storage Account creation.

On the “Data protection” tab of storage account creation:

• Disable “soft delete for blobs”
• Enable “Versioning for blobs” 
  • Select “Keep all versions”
•  Disable “Version-level immutability support”

Set “Blob public access” to Disabled and create a container. Give the container a name and set the “Public Access Level” to “Private”.

Container-Level Setting

After creating the Storage Account with the required settings, create a new container with the following setting:

• Expand the Advanced section, and Enable “Version-level immutability support”

Notes:

Do not configure lifecycle management policies for the container`s data.

Do not enable any default immutability policy at the storage account level.

After the Container is created, go to Security → Networking, Access Keys and copy the key1 key.
