Thanks for posting your question in the Microsoft Q&A forum.
To allow all systems connected to your corporate network to access your Azure storage account without individually adding IP addresses, you can use a combination of virtual network service endpoints and point-to-site VPN.
Configure a Virtual Network in Azure and set up VPN Gateway and then configure your storage account.
Remember to also configure proper authentication and authorization for your storage account, such as using Azure Active Directory for access control
