On Tuesday, April 25, 2023, at approximately 4:21 PM ET, Microsoft reported via tweet @MSFT365status that they were investigating an issue that was impacting Exchange Online connectivity for users in North America.

For system admins and IT professionals with access to the Microsoft 365 Admin Center, the service incident number to reference is EX546390.



Responses on Twitter from the Microsoft community were as expected, especially given this is the second issue reported by Microsoft in the past 24-hour period.  The prior issue was reported by Microsoft yesterday, April 24th, as service incident MO545600, which involved issues with search functionality in various Microsoft 365 services.  Many responses on Twitter were very critical of the frequency of outages and service incidents.

No community responses on Twitter gave any indication of whether or not the current Exchange Online connectivity issues extended beyond the North American region.

And approximately 60 minutes after first reporting the issue, Microsoft sent a second tweet announcing that the issue, thanks to their automated recovery systems, was resolved.



At approximately 6:00 PM ET, a check of the Microsoft Service Status page gave no indication of any ongoing issues.


The Importance of Microsoft 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.
