Hospitals in the West of England are experiencing disruption following a global Microsoft Outlook email outage, BBC reports.
The technical issue has affected communications at NHS trusts, raising concerns about the potential impact on appointments, enquiries and day-to-day operations.
The outage is affecting services including Teams, Outlook and Copilot across the world. Microsoft said the cause was "elevated load" on its server infrastructure.
Bristol NHS Foundation Trust reassured patients that essential hospital services and procedures were continuing as normal. Patients with urgent enquiries were advised to contact the relevant hospital department using the number on their appointment letter.
In a statement, Gloucestershire NHS Foundation Trust said it was aware of the outage and staff were "temporarily unable to send or receive emails".
"If you need to contact us urgently, please call the relevant clinic or switchboard directly rather than sending an email. Thank you for your patience," they added.
Bath and North East Somerset, Swindon and Wiltshire (BSW) Community Health said its services were also continuing to operate under "tried and tested business continuity plans".
