The news of an outage impacting Microsoft 365 services surfaced after customers reported experiencing issues while trying to sign into, access, and receive emails in the Outlook portal and via Exchange Online.
After widespread complaints of down or sluggish email services, Microsoft identified the problem and resolved the issue.
“We identified a section of our network infrastructure that was performing below acceptable thresholds. We’ve rerouted connections to alternate infrastructure and that confirmed the issue is resolved,” tweeted Microsoft.
The outage began late on Monday morning and continued till early afternoon before Microsoft fixed the problem.
Microsoft had identified availability drops within its network telemetry. Upon analyzing the network infrastructure to isolate the source of the issue, it was identified that a network router was not performing up to the acceptable thresholds.
Microsoft re-routed user connections to alternate devices and the telemetry monitoring indicated that the service had recovered. Microsoft also conducted extended monitoring to ensure that the issue is resolved. Microsoft’s https://portal.office.com/servicestatus now states that all services in the Outlook portal and Exchange Online are up and running.
