Microsoft's massive M365 outage stretches past 15 hours as its fixes keep failing
Hasn't completely ruled out cyberattack as cause of incident that's damaged Exchange Online and services that rely on it
Microsoft has been grappling with a massive M365 outage that has persisted for over 15 hours, causing widespread disruption to its online services. The issue began on Thursday at around 18:00 UTC, rendering email, Teams meetings, cloud PCs, Copilot, and 15 other hosted services inaccessible for Microsoft 365 users. Initially, the company attributed the problem to servers failing automated health checks, but later admitted that their attempts to resolve the issue had not yielded the expected results.
Despite various attempts, such as infrastructure capacity improvements and scaling up virtual machines, the outage persists, with Microsoft reporting partial recovery in certain regions but no sustained improvement. The company continues to investigate the root cause, stating that it is not aware of any malicious activity, and is taking a cautious approach to restore service.
As of now, users in Australia and surrounding areas are among those still unable to connect to multiple Microsoft 365 services.
