我们正在使用流事件从Office 365中不同用户的EWS获取通知

为此，我们制作了一个订阅管理器来管理到不同服务器的连接。打开订阅的调用如下所示：

_Connection = new StreamingSubscriptionConnection(_Service, 30);
// Add connections to the queue
foreach (var subscription in pendingSubscribes)
{
    _Connection.AddSubscription(subscription);
}
if (_Subscriptions.Count > 0) _Connection.Open();

这就像一个符咒，但现在，代码不会在某个O365邮箱的

Open

调用上恢复。所有其他测试邮箱都正常工作

该流已正确注册：

响应主体不会立即返回，因为连接保持打开状态

但是，对于不工作的邮箱，响应Http头根本不会返回

什么会导致这个问题？API不应该返回有效数据或错误消息吗？

您可能只是遇到了并发连接问题（这是最常见的错误），例如，如果您没有设置，则无法打开超过2个连接。我建议的另一件事是，您可以使用ewsdeditor@GlenScales测试该邮箱。您知道单个Office 365租户可以参与的Exchange服务器的最大数量吗？或者我可以安全地将ConnectionLimit设置为30k吗？如果您使用模拟，那么您不应该遇到并发问题
