Since about 2 AM today, we are seeing connection failures (EHLO timeout) to outlook.com MX servers, causing messages to be deferred. Since around 1 PM, this seems to be affecting more and more connections. This behavior is intermittent, some messages get through on the first attempt. In effect however, thousands of messages are delayed.
When such an event occurs, we log an Attempt for the associated message. That message will be retried after 10 minutes, then 30, then 60. The 60 minute retries will continue for 48 hours.
If you did not receive any mail after those 48 hours, please try again.
