From your existing Office 365 instance where you created your Dynamics CRM Online trial, you can add this additional trial service. Start by navigating on the left navigation area to BILLING | Subscriptions.

Select Add subscription on the top-right side of the screen. You are now presented with a listing of available subscriptions you can add to your existing instance. Scroll until you find the Enterprise Suite area and find Office 365 Enterprise E3.
