Microsoft said on Saturday, November 14, that it had restored service to customers and regions hit by a global Microsoft 365 outage that lasted more than 24 hours. Outlook, Teams and Copilot were among the applications affected.
“We have completed our efforts to address the underlying issue of the incident and restored service to the remaining impacted customers and regions,” the company said in a post on X. DW reported that Microsoft attributed the disruption to server issues and said it was not aware of outside interference behind the incident.
Reports of problems began on Thursday, November 12, with users and organizations in multiple countries unable to rely on services for email and online meetings. The outage affected businesses and government agencies, though the extent of the disruption varied.
Germany’s Federal Ministry for Digital Transformation and Government Modernization said the incident did not have a major effect on federal government functions but significantly affected German businesses. Britain’s National Health Service was also reported to have faced serious disruption, with staff turning to paper records.
Microsoft’s restoration announcement ended the service disruption, though the company’s statement did not specify how the technical issue began. The incident was described as one of Microsoft’s longest outages and its second major outage of the year.
