Microsoft Dynamics CRM has a number of roles. One of these roles is the sandbox service, which runs custom code. Many of our PowerPack Add-ons for Dynamics CRM contain plugins that run inside the sandbox. If the sandbox is misconfigured or even missing best practices there is a good chance the sandbox service will not work or not run efficiently. To help you get the most out of your sandbox service, we’ve compiled a list to help you verify that all items related to the sandbox are set up properly. Take a look!
