exchange-server - SubscribeToStreamingNotifications 中的异常

问题描述

我现在收到邮箱异常已经有一段时间了，自上个月以来甚至没有一次成功订阅流媒体。

例外： 无法连接到用户邮箱数据库 guid：67f43d90-xxxx-xxxx-xxxx-7a296a993f38 的邮箱，因为 ExchangePrincipal 对象包含过时的信息。邮箱最近可能已被移动。

我创建订阅的代码：

 private void CreateSubscription()
        {
            var events = new List<EventType>
            {
                EventType.NewMail,
                EventType.Created,
                EventType.Deleted,
                EventType.Modified,
                EventType.Moved,
                EventType.Copied,
                EventType.FreeBusyChanged
            };

            if (_subscription != null)
            {
                ((StreamingSubscription)_subscription).Unsubscribe();
                _connection.RemoveSubscription((StreamingSubscription)_subscription);
            }

            _subscription = _exchange.SubscribeToStreamingNotifications(subscriptionFolders, events.ToArray());
            _connection.AddSubscription((StreamingSubscription)_subscription);

            if (stopwatch.IsRunning)
            {
                stopwatch.Restart();
                var e = stopwatch.ElapsedMilliseconds;
                logger.LogFatal($"Stopwatch restarted: {e}");
            }
            else
            {
                stopwatch.Start();
                var e = stopwatch.ElapsedMilliseconds;
                logger.LogFatal($"Stopwatch started: {e}");
            }
        }

异常发生在以下行：

_subscription = _exchange.SubscribeToStreamingNotifications(subscriptionFolders, events.ToArray());

堆栈跟踪：

Microsoft.Exchange.WebServices.Data.ServiceResponseException: The specified object was not found in the store., Can't connect to the mailbox of user Mailbox database guid: 67f43d90-xxxx-xxxx-xxxx-7a296a993f38 because the ExchangePrincipal object contains outdated information.

请注意，我可以从邮箱中提取电子邮件，但无法创建流订阅。

解决方案

这是 OnPrem 还是 Office365？作为一般规则，您应该始终使用 X-AnchorMailbox 标头https://blogs.msdn.microsoft.com/webdav_101/2018/06/16/best-practices-important-and-critical-headers-for-ews/，该错误指示路由问题或过时的目录信息（可能由 AD 中的复制问题引起）。如果它的 Office365 尝试将 MailboxGUID 作为 X-AnchorMailbox https://developer.microsoft.com/en-us/office/blogs/error-improvement-for-invalid-x-anchormailbox-in-rest-api-calls/
