當郵件無法使用連接器從您的組織傳送至您的內部部署或夥伴電子郵件伺服器時,郵件會在 Microsoft 365 中佇列。When messages can't be sent from your organization to your on-premises or partner email servers using connectors, the messages are queued in Microsoft 365. 導致此狀況的常見範例如下:Common examples that cause this condition are:

  • 連接器設定不正確。The connector is incorrectly configured.
  • 您的內部部署環境中已有網路或防火牆變更。There have been networking or firewall changes in your on-premises environment.

Microsoft 365 會繼續重新嘗試傳遞24小時。Microsoft 365 will continue to retry to delivery for 24 hours. 24小時後,郵件會到期,並且會傳回未傳遞回報中的寄件者 (也稱為 NDRs 或退回的郵件) 。After 24 hours, the messages will expire and will be returned to the senders in non-delivery reports (also known as a NDRs or bounce messages).

如果佇列中的電子郵件磁片區超過預先定義的臨界值 (預設值為200郵件) 中,則可在下列位置取得此資訊:If the queued email volume exceeds the pre-defined threshold (the default value is 200 messages), the information is available in the following locations:

在郵件流程儀表板中佇列洞察力Queues insight in the Mail flow dashboard

即使已排入佇列的郵件磁片區未超出臨界值並產生警示,您仍然可以使用 郵件流程儀表板中的 佇列 洞察力,以查看佇列中超過一小時的郵件,並在佇列郵件數目變得太大之前採取動作。Even if the queued message volume hasn't exceeded the threshold and generated an alert, you can still use the Queues insight in the Mail flow dashboard to see messages that have been queued for more than one hour, and take action before the number of queued messages becomes too large.
