New Delhi: A massive global technical outage hit tech giant Microsoft on Thursday, disrupting critical platforms and leaving millions of users struggling to access their email accounts and workplace applications.
The disruption severely impacted major productivity tools, with Downdetector—a popular website that tracks service outages—reporting an influx of complaints. Shortly after 1:00 PM, nearly 1,30,000 users logged issues specifically related to Microsoft Outlook. While the volume of complaints gradually decreased, a significant number of individuals reported ongoing struggles with loading their inboxes, as well as an inability to send or receive emails.
The technical snag was not limited to Outlook alone. Thousands of professionals relying on the Microsoft ecosystem faced frustrating interruptions across various services, including the workplace messaging app Microsoft Teams, the AI assistant tool Copilot, and several other integrated features of Microsoft 365.
Taking to the social media platform X, the Redmond-based tech titan officially confirmed the development. Acknowledging the disruptions, the company stated, “Users in the Americas region are experiencing issues accessing Exchange Online mailboxes through various channels.”
According to Microsoft’s preliminary investigation, the root cause of the widespread connectivity issues was an “abnormally high load” on a specific portion of its infrastructure. The company revealed that a technical glitch encountered during an automated health check protocol caused multiple servers to abruptly go offline.
To manage the situation, the official Microsoft 365 Status account posted updates on X, reassuring users that teams were actively working to resolve the issue. The company stated that it was applying an alternative testing method to bring the affected servers back online and mitigate the overall impact.
Interestingly, the global disruption occurred just hours after Microsoft had claimed to have successfully resolved prior issues related to Teams in North America, though some users had still reported lingering connectivity troubles at the time. The widespread outage has once again highlighted the world’s heavy reliance on centralised digital infrastructure and the cascading effects of sudden server failures.
