Hi,
You can log into the Azure Portal using personal outlook account, navigate to Microsoft Entra ID and create a new cloud user directly within default tenant directory. Because the primary subscription email is an external identity, the directory domain will automatically default to an organizational string like .onmicrosoft.com. You can configure a clean identity such as dbadmin@ushakaleclouddbaoutlook.onmicrosoft.com and securely record its temporary password.
Once the new identity is created, click into the new user's profile within Entra ID, navigate to assigned roles and add the Global Administrator role to this new account. Move to the Azure Subscription or the specific Resource Group that runs the Premium Databricks workspace. Click into Access Control (IAM), select add role assignment, and grant this newly created organizational user the Owner or Contributor role to ensure that the identity possesses full administrative authority over the underlying Azure cloud infrastructure assets before you attempt to map any services.
You can open a completely new incognito browsing window and login with the new account created and navigate directly into the Databricks Account Console where you can navigate to Data, build your East US metastore, link it to your workspace and successfully run CREATE CATALOG commands
