自定义工作流程步骤不一致的行为

我做了一个自定义工作流程步骤，它将电子邮件发送给用户组。我采取预先创建的电子邮件和程序发送：自定义工作流程步骤不一致的行为

if (recepients.Entities.Any()) 
    { 
     Entity email = service.Retrieve("email", mailId, new ColumnSet(true)); 

     email.Attributes["to"] = recepients.Entities.ToArray(); 

     service.Update(email); 

     SendEmailRequest sendEmail = new SendEmailRequest() 
     { 
      EmailId = mailId, 
      IssueSend = true 
     }; 

     service.Execute(sendEmail); 
    }

的问题是 - 它工作在同步模式就好了，并抛出一个“无效的转换”异常，如果我转换成工作流程和异步尝试运行它。

这里什么跟踪日志服务器上的规定：在工作流程的转换结果发生

>System.InvalidCastException: Microsoft Dynamics CRM has experienced an error. Reference number for administrators or support: #EBCA9EC1: System.InvalidCastException: Specified cast is not valid. 

> at Microsoft.Crm.Common.ObjectModel.TrackingManager.GetNextTrackingToken(String subject, String& trackingToken) 

> at Microsoft.Crm.Common.ObjectModel.EmailService.Send(Guid emailId, Boolean issueSend, String trackingToken, ExecutionContext context)

莫名其妙的错误。我应该在哪里寻找这个问题的根源？

你如何在服务您的自定义工作流步骤它是否在执行用户的上下文中运行？ –

@Henrik我使工厂脱离执行上下文，然后使用SYSTEM权限创建IOrganizationService实例。 – user3032348

尝试创建运行作为执行用户的OrganizationService，代替SYSTEM。与核心电子邮件操作类似的问题已经经历了由Andrii Butenko, who concluded that it works when running the service in the context of the executing user.

我已经改变服务的实例在运行用户，一切都没有任何问题的工作：

IOrganizationServiceFactory factory = 
    (IOrganizationServiceFactory)serviceProvider.GetService(typeof(IOrganizationServiceFactory)); 
IOrganizationService service = factory.CreateOrganizationService(executioncontext.UserId);
