A major global Microsoft service disruption has affected healthcare operations across the United Kingdom, disrupting communication between hospitals, general practitioners (GPs) and pharmacies, while raising concerns about delays in patient referrals, prescription processing and other administrative services.
The outage, which began on Thursday, November 12, 2026, has affected several Microsoft platforms, including Outlook, Microsoft Teams, OneDrive, SharePoint and other Microsoft 365 services.
The disruption has spread across multiple countries, affecting businesses, government institutions and public services that depend on Microsoft’s technology infrastructure.
In the UK, healthcare organisations have reported difficulties accessing email systems and other digital tools used to coordinate patient services, prompting some NHS facilities to advise patients to use telephone communication for urgent enquiries.
The incident has also highlighted the risks associated with the growing dependence of essential public services on a relatively small number of major technology providers.
NHS Services Face Communication Disruptions
Britain’s National Health Service (NHS) has been among the organisations affected by the Microsoft outage, with disruptions reported across hospitals, GP practices and other healthcare facilities.
According to reports by The Guardian, NHS staff have experienced difficulties accessing Microsoft services, particularly email and communication platforms used for administrative coordination.
The disruption has affected communication between healthcare professionals and organisations responsible for managing patient referrals, appointments and prescriptions.
Pharmacies have also reported difficulties communicating with GP practices, potentially delaying the processing of medication requests and increasing waiting times for some patients.
The National Pharmacy Association warned that communication problems between pharmacies and medical practices could affect patients waiting for prescriptions.
The situation has created additional administrative pressure for healthcare providers, particularly those that depend on digital communication to exchange patient information and coordinate services.
However, the extent of the disruption varies between healthcare organisations, and reports indicate that not all clinical services have been affected.
Patients Advised to Contact Healthcare Providers by Telephone
Several NHS organisations have issued public notices advising patients to avoid relying on email for urgent communication while Microsoft works to restore affected services.
Lincolnshire Partnership NHS Trust confirmed on November 13 that it was experiencing problems with email and other Microsoft products.
The organisation advised patients requiring urgent referrals or crisis support to contact its services by telephone rather than email.
Similarly, University College London Hospitals NHS Foundation Trust announced that access to Outlook and other Microsoft platforms had been affected, preventing some staff from sending and receiving emails.
The hospital advised patients requiring urgent assistance to contact the relevant clinic or switchboard directly.
Other healthcare facilities have also warned that delays could affect responses to patient enquiries, hospital correspondence and referral processing.
Brunton Park Health Centre confirmed that although its clinical systems remained accessible, disruption to email and Microsoft Teams could affect communication with external organisations and delay specialist referrals.
These notices demonstrate how a disruption affecting communication infrastructure can create operational challenges even when hospitals and medical practices retain access to their core clinical systems.
Prescription Delays Raise Concerns for Patients
One of the significant consequences of the outage is the potential disruption to prescription processing.
Pharmacies frequently communicate with GP practices to confirm prescriptions, resolve medication queries and obtain information required to dispense medicines.
When these communication channels become unavailable, some administrative processes can take longer than usual.
The National Pharmacy Association indicated that difficulties communicating with GP practices could increase waiting times and delay some prescriptions.
The disruption has also affected access to certain digital systems used by healthcare professionals.
In some facilities outside the UK, medical organisations have reportedly resorted to paper-based prescription procedures as a temporary alternative when authentication systems became unavailable.
Although these arrangements can help maintain essential services, they may introduce additional administrative work and slow down normal operations.
For patients who depend on regular medication, the situation reinforces the importance of having alternative arrangements for obtaining prescriptions during major technology disruptions.
Healthcare providers have encouraged patients to follow instructions issued by their individual practices rather than assuming that every NHS service has been affected in the same way.
Microsoft Struggles to Restore Affected Services
Microsoft has been working to restore its services following the widespread disruption.
The company’s updates indicated that the incident involved infrastructure and server-related problems affecting the availability of Microsoft 365 services.
The technology company reported difficulties involving server availability, traffic management and infrastructure capacity.
Its initial recovery efforts encountered problems, with some changes introduced to improve service availability failing to produce the expected results.
Microsoft subsequently explored alternative technical measures to increase capacity and improve the stability of affected systems.
The company also reported early signs of improvement following infrastructure adjustments and efforts to stabilise its servers.
However, service recovery has been gradual, with users continuing to experience intermittent problems in some locations.
Microsoft said it had no indication that malicious activity or a cyberattack caused the disruption.
The company is expected to provide further information about the incident, including its underlying cause and measures intended to prevent similar problems.
The official Microsoft service health platform has continued to provide information about the condition of affected services.
Outage Extends Beyond Healthcare
Although the disruption has attracted particular attention because of its implications for healthcare, its effects have extended to several other sectors.
According to reporting by The Associated Press and The Guardian, the outage has affected government institutions, police forces, educational organisations and businesses across different countries.
In the UK, several police forces reported difficulties receiving online crime reports and other communications submitted through their websites.
Some forces advised members of the public to use telephone services for time-sensitive reports while the technical problems continued.
Schools and universities also experienced communication difficulties, with some institutions warning parents, students and staff that access to email and collaboration platforms could be limited.
Government departments have been assessing the potential impact on their operations, with officials working alongside Microsoft to minimise disruption.
The effects have also extended internationally.
Organisations in countries including Australia, Japan, Singapore and the United States have reported problems involving Microsoft services.
Airlines and other businesses have experienced communication difficulties, although some major transport operations have continued functioning normally.
The international reach of the incident illustrates how technology infrastructure operated by a single company can support services across multiple industries and geographical regions.
Why the Microsoft Outage Matters to Healthcare
The incident raises important questions about the resilience of healthcare systems in an increasingly digital environment.
Hospitals and medical facilities increasingly depend on cloud-based communication platforms, electronic records, digital appointments and interconnected administrative systems.
These technologies improve efficiency, support information sharing and help healthcare professionals coordinate services.
However, the disruption demonstrates that dependence on digital infrastructure can create vulnerabilities when a major provider experiences technical problems.
Even when essential medical equipment and clinical systems remain operational, the inability to exchange information quickly can affect administrative processes that support patient care.
For example, delayed communication between a GP practice and a specialist hospital could slow down the movement of referral information.
Similarly, difficulties exchanging prescription details could create additional work for pharmacists and healthcare professionals.
The situation also highlights the importance of maintaining alternative communication channels that can function independently of major cloud service providers.
Telephone systems, secure backup communication platforms and documented manual procedures can help organisations maintain essential operations during technology failures.
For healthcare providers, these arrangements are particularly important because delays in communication can have consequences for patients who require timely medical attention.
Cybersecurity Concerns and the Need for Infrastructure Resilience
The outage has also renewed discussions about cybersecurity, technology reliability and the concentration of digital services among major providers.
Although Microsoft has said there is no indication that the incident resulted from a cyberattack, the disruption demonstrates that technical failures can produce consequences comparable to those associated with other major digital incidents.
Organisations that rely heavily on cloud-based services must consider not only cybersecurity threats but also infrastructure failures, software configuration problems and unexpected service interruptions.
The incident also brings renewed attention to the 2024 CrowdStrike disruption, which affected computer systems across multiple industries and demonstrated how technology failures can have widespread operational consequences.
While the circumstances of the two incidents are different, both highlight the importance of testing software changes, maintaining contingency arrangements and preparing for unexpected disruptions.
For governments and healthcare organisations, resilience requires more than purchasing digital services. It also involves ensuring that essential operations can continue when those services become unavailable.
What Happens Next?
Microsoft’s immediate priority is to restore the affected services and improve infrastructure stability.
The company has reported progress in its recovery efforts, although the restoration process has not been uniform across all services and regions.
Meanwhile, affected NHS organisations are continuing to monitor the situation and use alternative communication arrangements where necessary.
Patients have been advised to contact their healthcare providers directly by telephone when dealing with urgent matters, particularly where email communication may be unreliable.
Importantly, patients should not automatically assume that scheduled hospital appointments have been cancelled because of the outage.
Several NHS facilities have specifically advised patients to attend appointments as planned unless they receive different instructions.
The situation will depend partly on how quickly Microsoft restores normal service and how effectively individual healthcare organisations manage outstanding referrals, correspondence and prescription requests.
Further technical information from Microsoft should help establish the precise cause of the incident and identify measures required to reduce the risk of similar disruptions.
A Warning About Dependence on Digital Infrastructure
The Microsoft outage provides another reminder of the importance of reliable technology infrastructure in modern public services.
For Britain’s healthcare system, the immediate challenge is to maintain communication, minimise delays and ensure patients continue receiving necessary services while affected systems are restored.
Beyond the UK, the incident carries lessons for governments, businesses and healthcare institutions worldwide, including those across Africa, where digital transformation is increasingly shaping public administration and service delivery.
As organisations expand their dependence on cloud computing and interconnected technology platforms, investment in alternative systems and operational continuity will become increasingly important.
The ability to continue essential services during a major technology failure is now a critical part of institutional preparedness.
For patients and healthcare providers, the priority remains ensuring that technical disruptions do not become barriers to accessing necessary medical care.
