For this recipe, you will need the Visual Studio solution created in this chapter's Creating a Visual Studio Solution for Dynamics 365 customization, the early bound entities with the optionset enum values created in the Creating early bound entity classes and Extending CrmSvcUtil to generate optionsets enum recipes of Chapter 3, SDK Enterprise Capabilities, and the data access layer defined in Creating a LINQ data access layer from this chapter as well. None of those components are mandatory, but they form a good basis to build your plugin on.

To run the plugin, you need the appropriate access to the account and e-mail entities.
