Javascript 如何在Dynamics中使用Odata客户端设置电子邮件的发件人和收件人？

我正在尝试使用Dynamics中的活动方概念将发件人和收件人添加到电子邮件中。我使用的是简单的Odata客户端。但我得到了以下错误：

消息：“Create”方法不支持“activityparty”类型的实体。”

代码：

parties = [];
var sender = {};
var recipient = {};
sender["partyid_systemuser@odata.bind"] = "/systemusers(37d4b5e8-f0c8-e911-a976-000d3a13cdfe)";
sender["participationtypemask"]= 1; 
recipient["partyid_systemuser@odata.bind"] = "/systemusers(37d4b5e8-f0c8-e911-a976-000d3a13cdfe)";
recipient["participationtypemask"]= 2; 
parties.push(sender);
parties.push(recipient);
entity["email_activity_parties"] = parties;

确保您没有使用诸如

/api/data/v8.0/activityparties

之类的url来创建活动实体。您应该始终将单个活动类型定位为

电子邮件

或

任务

或

电话呼叫

，就像端点

/api/data/v8.0/emails

，因为所有单个活动都将在后台创建

活动参与者

。

您不能直接创建活动方实体记录，因为该实体仅支持

RetrieveMultiple

消息，而不支持

create

或

Update

您能提供完整的代码吗？魔鬼可能在细节中。另外，这里有一篇文章描述了这个过程：添加了代码@ShaamaanI'm Middle。您提供的初始代码显然是JS。现在您已经添加了C#代码。只是慢点你到底想做什么？而且，如果使用C#，那就是一些奇怪的查询和执行。您正在使用官方SDK吗？
