Office 365 Monitoring: Mailflow Outage (April 22, 2021)

Written by ENow Software | Apr 22, 2021 4:46:29 PM

On April 22, 2021, at ~2:55 pm UTC, Microsoft reported a potential Exchange Online mailflow incident impacting users in North America.

Many Twitter users soon chimed in stating that this "potential" issue was in fact a real issue for their organization.


Roughly an hour after the "potential" issue was reported, Microsoft announced they had identified the root cause. In this case,  a load balancing configuration issue was the culprit and Microsoft was actively working on resolving the issue. 

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.
