Roughly an hour later, Microsoft reported that Outlook on the web seemed to be primarily affected and suggested that user’s workaround the problem by using alternate methods. Soon after, they reported the issue was stemming from a recent update that was causing issues with authentication. They disabled the problematic update to mitigate impact and were monitoring the situation.


Finally, at 8:00pm UTC Microsoft reported that the change to disable the problematic update had been completed and confirmed that the issue was resolved.



The Importance of Office 365 Monitoring

In a cloud-world, outages are bound to happen. While Microsoft is responsible for restoring service during outages, IT needs to take ownership of their environment and user experience. It is crucial to have greater visibility into business impacts during a service outage the moment it happens.

ENow’s Office 365 Monitoring and Reporting solution enables IT Pros to pinpoint the exact services effected and root cause of the issues an organization is experiencing during a service outage by providing:

  • The ability to monitor entire environments in one place with ENow’s OneLook dashboard which makes identifying a problem fast and easy without having to scramble through Twitter and the Service Health Dashboard looking for answers.
  • A full picture of all services and subset of services affected during an outage with ENow’s remote probes which covers several Office 365 apps and other cloud-based collaboration services.
