Microsoft outage hits Outlook, Teams and Copilot worldwide

Microsoft’s Outlook, Teams and Copilot remained unavailable for more than 12 hours on Friday, Business Recorder reported, disrupting organisations across several countries. The company attributed the incident to server problems, said it had found no indication of malicious activity and reported signs of improving stability after deploying fixes more widely.

The disruption affected government bodies, trading firms, airlines and financial businesses, with some organisations facing email problems and delayed communications. Euronext reported difficulties for its listing teams, while a Taiwanese financial company reportedly used fax to confirm trades; Workhorse Group moved its results announcement to November 16. Microsoft said parts of Microsoft 365 reliant on Exchange Online were affected, while other features continued to work. The outage was the second disruption to Microsoft 365 services this year.
