Office 365 Users Unable to Log On with Multi-Factor Authentication


At approximately 10:30 PM CDT on November 18, 2018, Office 365 Multi-Factor Authentication services went down preventing users with this vital security service from being able to sign on. Microsoft reports a hot-fix being rolled out, but states it could take some time with updates published hourly at the Office 365 Service Health Status.

Nothing has been publicized by main-stream media, but harsh criticism has been posted by The Inquirer, Computer Business Review, and TechCrunch. Of those only The Inquirer uses Office 365 and the other two appear to be paid advertising by Mimecast.

As streamlining technology is about avoiding risks, we purposefully don’t implemented updates or changes over a weekend or holiday so revenues aren’t lost and users don’t go looking for pitchforks and torches.
