StreamingSubscriptionConnection.Open挂起一个O365邮箱

Question

我们正在使用流式事件从Office 365中的不同用户的EWS收到通知。

为此，我们建立了一个订阅管理器来管理与不同服务器的连接。打开订阅的调用如下所示：

这就像一个魅力，但现在，代码不会通过_Connection = new StreamingSubscriptionConnection(_Service, 30); // Add connections to the queue foreach (var subscription in pendingSubscribes) { _Connection.AddSubscription(subscription); } if (_Subscriptions.Count > 0) _Connection.Open(); 调用某个O365邮箱恢复。所有其他测试邮箱都有效。

Stream已正确注册：

Open

然后我们打开StreamingConnection。这就是它查找工作邮箱的方式：

响应正文不会立即返回，因为连接保持打开状态。

但是，对于非工作邮箱，Response Http Headers根本不会回来。

可能导致此问题的原因是什么？ API不应该返回有效数据或错误消息吗？
