Global Microsoft Outage Disrupts Email, Teams and Essential Services

A widespread outage affecting Microsoft platforms has disrupted access to email accounts and triggered technical errors across several of the technology giant’s widely used applications, leaving thousands of users and organisations struggling to carry out routine operations.

The disruption has extended well beyond personal inboxes, with businesses and government agencies reporting significant interruptions to their day-to-day administration. Some stores have lost access to email-based sales, patients have been unable to use telehealth services, and long-distance schools have been forced to suspend classes for the day.

Thousands of users have also reported problems with Microsoft Teams, its workplace messaging platform, AI assistant Copilot and various Microsoft 365 services.

Microsoft said it was not aware of any malicious activity linked to the outage.

In an update shortly after 9am AEST, the company said it had begun a gradual recovery of access to email and other online services. However, the improvement was short-lived, with a subsequent update about an hour later reporting that some restored servers had become unresponsive again.

Microsoft explained that a process on the affected servers responsible for establishing secure connections had become overwhelmed, preventing the servers from processing requests.

The company said it was preparing a fix to address the behaviour. If successful, it planned to gradually reintroduce additional traffic to the affected services.

In a further message, Microsoft acknowledged the disruption and thanked organisations for their patience, saying it was working urgently to resolve the incident.

The company also said investigations were continuing to identify the underlying cause of the outage and determine why changes were not synchronising correctly.

Its latest update reported positive results in efforts to improve server stability, following an earlier assessment that described progress as marginal.

The incident highlights how heavily businesses, public services and everyday users rely on Microsoft’s cloud-based platforms, with a disruption to a major technology provider capable of affecting essential services across multiple sectors.
