The Microsoft outage has caused widespread disruption across UK public services, with hospitals, GP surgeries, police forces, and property agents all affected. The IT failure, which impacted Microsoft 365 services including Outlook, Teams, SharePoint, OneDrive, and Copilot, left many unable to access emails, calendars, and critical patient data.
How the Microsoft Outage Unfolded
The problems began in the early hours of Friday morning, with NHS staff first noticing issues accessing emails. By 6am, the severity became apparent as hundreds of hospitals, GP surgeries, and community health services reported serious disruption. The NHS.net Connect system, used by over a million NHS staff for emails, meetings, and file access, is powered by Microsoft and was severely affected.
Senior health sources described the disruption as "serious" and "widespread." The Medicines and Healthcare products Regulatory Agency also experienced problems sending and receiving emails. Some staff resorted to using paper records after being unable to access digital systems.
Impact on Healthcare Services
The NHS faced significant challenges as the outage prevented many staff from logging in, performing basic duties, or sending and receiving patient data needed for healthcare delivery. An NHS England spokesperson acknowledged the disruption, stating that local contingency plans were enacted.
Doctors and hospital workers reported being unable to access Microsoft 365 services, which are integral to daily operations. The outage affected not only email but also collaboration tools like Teams and file-sharing platforms like SharePoint and OneDrive, hindering coordination among healthcare teams.

Police and Other Public Services Affected
Police forces across the UK also reported issues, with some unable to access email systems and other IT facilities. Property agents were similarly impacted, unable to process transactions or communicate with clients effectively. The broad impact underscores the reliance of public services on Microsoft's cloud-based infrastructure.
The outage highlighted vulnerabilities in critical systems, as many organizations had to revert to manual processes. This disruption comes at a time when public services are already under pressure, raising questions about resilience and backup plans.
Key Takeaways for Public Services
- Critical dependence on Microsoft 365: The outage revealed how deeply public services rely on a single provider for email, collaboration, and data storage.
- Contingency plans were activated: Many organizations switched to paper records and manual procedures, but these are not sustainable long-term.
- Patient data access was hindered: Healthcare delivery was impacted as staff could not access or share patient information electronically.
- Communication breakdowns: Police and property agents faced challenges in coordinating and serving the public.
- Need for resilience: The incident raises questions about the adequacy of backup systems and the risks of centralized IT infrastructure.
Comparing the Disruption Across Sectors
| Sector | Affected Services | Impact Severity | Contingency Measures |
|---|---|---|---|
| Healthcare (NHS) | Email, Teams, SharePoint, patient data systems | Serious and widespread | Paper records, manual processes |
| Police | Email, IT facilities | Moderate to severe | Limited communication alternatives |
| Property Agents | Email, transaction processing | Moderate | Delayed transactions |
| Regulatory Agencies | Moderate | Alternative communication channels |
What This Means for the Future
The Microsoft outage serves as a wake-up call for public services to diversify their IT infrastructure and invest in robust backup systems. As organizations recover, the focus will likely shift to enhancing resilience and reducing single points of failure.
For now, services are working to restore normal operations, but the incident has exposed the fragility of digital dependencies. The UK government may face calls to review its IT contracts and ensure that critical services can withstand such disruptions.
