Additional email that could be retrieved from the system has been sent. As a result, a larger share of messages that initially did not go through (and that had triggered messages to the sender that they were not delivered) has made it to the intended recipients.\n\nHowever, there is a possibility that any given email that triggered a non-delivery message to the sender did not get re-queued. We recommend that anyone who received a non-delivery message for an important email and who has not already re-sent it should do so. We apologize for the inconvenience and any duplication this may cause. Additional email that could be retrieved from the system has been sent.

Cornell engineers have found a way to deliver a share of email that did not make it through the system during yesterday’s issues. These will be sent over the next few hours and will result in recipients getting messages that have been delayed, and in some cases, they may receive a duplicate of mail that has already been delivered to them. We apologize for any confusion or inconvenience this may cause.\n\nBackground: \nThe issue appears to have been caused when custom settings that exist to provide added features to the Cornell email environment needed to be adjusted to work with the updated Microsoft system, resulting in some email being delayed and some not being delivered. As indicated in a previous update, senders whose email was not delivered were notified. \n\nThe issue appeared around 10:30am on Wednesday, April 8, 2015, and the process of adjusting settings was largely concluded by 12:30pm. By around 3:30pm, much of the email delivery that could be made possible by those fixes had been delivered. As noted above, a way has been found to release more undelivered email, and that is currently underway.\n \nEngineers are still evaluating the extent of the issue and identifying the messages that were affected. An update will be provided when next steps have been identified. Cornell engineers have found a way to deliver a share of email that did not make it through the system during yesterday’s issues.
