To activate Sandbox as a Service, obtain the Activation Code from your Trend Micro sales representative or reseller and provide the Activation Code on the Customer Licensing Portal.
If you have not activated the license for Sandbox as a Service or your license expires, all your Virtual Analyzer settings in virus and spam policies cannot take effect.
The License Key screen appears.
The My Products/Services screen appears and displays the updated license information.
Wait for some time because the license activation may take as long as 20 minutes to finish. If you keep seeing the error message about the Sandbox as a Service license after that, contact technical support for assistance.
