When you are deploying a storage account its not tied to a particular VNET. You have to enable the service endpoint Microsoft.Storage. This will allow you access to the Microsoft.Storage endpoint from that particular VNET. You can also specify allowed VNETs from within the storage account itself under Firewalls and virtual networks. This will allow you to specify VNETs, IP addresses, and a CIDR range if required. Hopefully this answers your question. If it does not let me know and I can go into further detail. @arani007
