Microsoft 365 features that help users manage their subscriptions, account settings, and billing information.
Since the old VLSC portal has been retired, and any remaining Volume Licensing information is now managed through the Microsoft 365 Admin Center. You can sign in to the organization's tenant and check Billing > Your Products to see any existing licenses or agreements.
If you cannot find the licenses there or do not have access to the correct tenant, you'll need to contact Microsoft Volume Licensing Support for assistance locating the old licensing records. (Contact Volume Licensing Support | Microsoft Learn)
