Hi @Filip ,

It's obsolete way of configuring access to storage account. Nowadays you should use UC and storage credentials and external location to configure access to storage account. 

A storage credential is a securable object representing an Azure managed identity or Microsoft Entra ID service principal. Once a storage credential is created access to it can be granted to principals (users and groups).Storage credentials are primarily used to create external locations, which scope access to a specific storage path
