    UPDATE Friday 7/1. The delays cleared last evening. Microsoft issued an alert to their customers: "we're continuing to revert a recent update which may have caused the infrastructure to operate below the expected threshold".The effect on CUIT systems was only that mail was queued up for several hours while re-trying delivery to the and Office 365 systems. Email is always re-tried for 3 days, so our servers automatically sent out to those systems once they were available.


    UPDATE 13:00. The unofficial source has about 100 reports of Outlook 365 problems since about 10:00 this morning. [correction: originally misstated as 1,000]


    UPDATE 12:45. A few messages have gone through to but for the most part the system is still giving the temp fail for both subdomains.


    Email for addresses and, both hosted on Outlook 365, cannot be delivered at this time. The mail server is returning "Temporary server error". The email is being queued and retried on our servers and will go through automatically when the server is able to take it.

    This affects cases where mail is sent to address and has to be re-sent to those subdomains.
