BSO Statement: Microsoft 365 service disruption update – 4pm

13 November 2026

Microsoft has reported continued recovery across much of Europe following a global disruption to Microsoft 365. Outlook email remains the main service affected for Health and Social Care (HSC) organisations in Northern Ireland. Some staff may still have intermittent difficulty accessing their inboxes, and emails to and from HSC teams may take longer than usual to arrive.

We understand Microsoft is working to stabilise affected services and clear the backlog of delayed emails. Some features in other Microsoft 365 services, including Teams and SharePoint, may still be affected. Microsoft says it has found no evidence of malicious activity linked to the disruption. A timescale for full restoration has yet to be confirmed.

The Business Services Organisation’s IT team continues to monitor the situation along all our regional HSC IT Colleagues and liaise with Microsoft.

If you need a timely response from an HSC service, please check appropriate websites and online information, alternatively call the service using its usual published telephone number. Please check your HSC organisation’s usual public channels frequently for any updates about individual services.

We recognise the inconvenience this is causing for patients, service users and staff, and wish to thank all our HSC colleagues for their due diligence and hard work today. We have not returned to ‘Business as Usual’ and will provide a further update when more information is available.
