Question

I've made a custom workflow step which sends email to the group of users. I take precreated email and send it programmatically:

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);
    }

The problem is - it works just fine in sync mode, and throw an "Invalid Cast" exception if i convert workflow into async and try to run it.

Here what trace log on the server provides:

>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)

Somehow error occurs during converting results of the workflow. Where should I look to find the root of this problem?

尝试创建作为执行用户运行的OrganizationService，而不是SYSTEM。 Andrii Butenko, who concluded that it works when running the service in the context of the executing user.

遇到了与核心电子邮件操作类似的问题

我已将服务实例化更改为正在运行的用户，所有工作都没有任何问题：

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