I made a plugin for email entity and registered it on Pre Create event (child pipeline). Plugin is as simple as possible:

```
public class AddDescription : IPlugin
{
    public void Execute(IPluginExecutionContext context)
    {
        DynamicEntity di = (DynamicEntity)context.InputParameters["Target"];

        di.Properties["description"] = "blabla";
    }
}

```

But description (=email body) stays the same. No exceptions are thrown. I debuged and it looks like Properties collection is changed ('blabla' description added) but it is not saved.

If I register the same plugin on account entity (Pre Create, child pipeline) it works fine.

Does email entity have any restrictions about changing properties on create?!!?

**EDIT (MORE INFO):**

I tried to change description, subject, category and subcategory and to my surprise category and subcategory changed while description and subject didn't.

tnx for help
bye
