Microsoft’s suite of productivity software, including services like Microsoft 365 and Azure, experienced a major outage affecting thousands of users worldwide on Thursday. This latest incident left many users unable to access critical work tools, sparking widespread frustration.
The outage was initially reported around 8 a.m. EDT, and it quickly spread across multiple services, leaving organisations and individuals stranded for several hours. The root cause of the disruption remains unclear, though Microsoft has confirmed that it is working with a third-party Internet Service Provider (ISP) to investigate the issue.

According to Downdetector.com, a website that tracks service outages, more than 20,000 people reported problems with Microsoft 365. The bulk of complaints came from users who could not access tools such as Microsoft Word, Excel, and Teams.
Teams, in particular, saw nearly 4,000 reports of disruptions, which affected communication and collaboration for numerous businesses. The effects of the outage were felt in real-time, as organisations that rely heavily on these services to manage their daily operations had to pause or find alternative solutions until service was restored.
Microsoft’s Response and Efforts to Fix the Problem
Microsoft’s X (formerly Twitter) account posted at 8:38 a.m. EDT, acknowledging the outage and assuring users that they were investigating the issue. The company’s statement noted that users may experience difficulties accessing multiple Microsoft 365 services. By 9:42 a.m. EDT, Microsoft updated its users again, stating that they were actively reviewing their network telemetry and making efforts to identify recent changes to the infrastructure.
In addition to their internal investigation, Microsoft revealed that it was working with a third-party ISP to better understand the underlying cause of the outage. While no specific time for recovery was provided, the statement indicated that Microsoft was focused on resolving the issue as quickly as possible.

This outage, however, comes at a time when users have grown wary of frequent service disruptions, as it follows a similar incident in July 2024. During the July outage, a distributed denial-of-service (DDoS) attack targeted Microsoft’s systems, and the company’s response efforts were delayed due to a technical error.
Although Microsoft has not yet disclosed whether this recent outage was due to similar malicious activity, the pattern of such incidents has raised concerns about the resilience of their cloud infrastructure.
Impact on Users and Organisations
The outage’s timing, occurring early on a weekday morning in the U.S., had a significant impact on productivity. Businesses using Microsoft 365 for critical operations, including cloud storage, communication, and data management, were severely affected.
With thousands of employees unable to access emails, collaborate on projects via Teams, or work on shared documents, many companies were forced to delay meetings, put work on hold, or resort to alternative tools, such as Google Drive and Zoom.
This disruption also highlighted the increasing dependence on cloud-based services like Microsoft 365 and Azure, which many organisations use for everything from basic office tasks to complex data processing.
The outage underscores the need for businesses to have contingency plans in place when these critical services go offline. Companies that did not have backup systems were especially vulnerable to the downtime, which could result in lost revenue, missed deadlines, and customer dissatisfaction.

AT&T customers appeared to be among the hardest hit by the outage, with multiple reports indicating that users of the telecom giant were struggling to connect to Microsoft services. This led to speculation that the issue could be tied to AT&T’s network infrastructure, although Microsoft has not officially confirmed this connection.
Lessons from Previous Outages and Microsoft’s Long-Term Plans
As Microsoft continues to investigate the cause of this most recent outage, it is worth noting that the company has already faced pressure to improve the reliability of its cloud services. In the aftermath of the July 2024 DDoS attack, Microsoft admitted that its response could have been quicker and more efficient, citing an internal error that exacerbated the problem.
The company has since been evaluating its security and operational protocols, seeking ways to avoid similar incidents in the future.
Additionally, Microsoft has been working on strengthening its system architecture to prevent large-scale disruptions. For example, the company is exploring ways to limit kernel access for third-party security vendors, a move that stems from a major outage earlier this year caused by a faulty software update from CrowdStrike. While Microsoft has not committed to closing off kernel access entirely, it is in the early stages of designing a more robust security platform that could reduce the risk of such incidents.
Industry experts have expressed mixed reactions to these proposed changes. On one hand, companies like Sophos, Trend Micro, and CrowdStrike have appreciated Microsoft’s collaborative approach to improving system stability and security.
However, some in the tech industry, such as Cloudflare CEO Matthew Prince, have raised concerns about potential antitrust implications. These concerns stem from the possibility that Microsoft could restrict kernel access for third-party vendors while continuing to offer privileged access to its own security products.
