We are retiring Azure AD Domain Services classic VNET support on 1 March 2023

In 2017, Azure AD Domain Services became available to host in an Azure Resource Manager network. Since then, we have been able to build a more secure service using the Azure Resource Manager’s modern capabilities. As Azure Resource Manager deployments fully replace classic deployments, Azure AD DS classic virtual network deployments will be retired on **1 March 2023**. **How does this affect me?** After **1 March 2023**, your current Azure AD DS classic virtual network deployment will be removed, and all applications using Azure AD DS will no longer function. **What actions should I take?** To avoid losing access to your managed domain, migrate Azure AD DS from your classic virtual network to an Azure Resource Manager virtual network before 1 March 2023.
