Global Microsoft outage disrupts HSE email, but patient services unaffected

The Health Service Executive (HSE) confirmed its email system is impacted by a global Microsoft outage, though patient services remain unaffected so far. The disruption also causes intermittent problems with Microsoft videoconferencing. Cork City Council reported email and other service disruptions, with its ICT team working on temporary solutions while awaiting Microsoft updates. Microsoft is racing to restore services after the worldwide outage, which began Thursday and continued into Friday, affecting Outlook, Teams, Copilot, and other Microsoft 365 products. Sinn Féin TD Máire Devine said the outage is affecting Oireachtas services, including email, preventing submissions to government departments until resolved. Microsoft has tried several fixes, including isolating infrastructure and shifting traffic, but confirmed changes are not performing as expected.
