The Government Technology Agency of Singapore announced on 14 November that Microsoft Outlook services for the Singapore Government had been fully restored since 11pm the previous evening. A GovTech spokesperson thanked members of the public for their patience and understanding.
The restoration came a day after a global Microsoft outage struck hundreds of thousands of users, hitting government agencies, banks and educational institutions in Singapore and beyond. The outage specifically affected Exchange Online, Microsoft's cloud-based e-mail and scheduling service, while applications not connected to it continued to function.
What was announced
Several statutory boards and agencies, including the Inland Revenue Authority of Singapore, Singapore Land Authority, SingHealth and the Singapore Police Force, posted on Facebook confirming their e-mail services were operational by the morning of 14 November.
The Immigration and Checkpoints Authority and Singapore Customs separately confirmed on the afternoon of 14 November that their FormSG submission service had resumed. FormSG is a government tool that allows public officers to create secure digital forms for data collection.
Banks DBS, UOB and Maybank also announced on their Facebook pages that their e-mail services had been restored, though core banking operations had remained unaffected throughout the disruption.
Scale of the outage
Reports of issues with Microsoft Outlook peaked at 1,135 at around 9.30am Singapore time on 13 November, gradually declining to 347 by around 8.45pm the same day. Globally, more than 7.4 million reports were logged worldwide, peaking at nearly 20,000 a minute — more than 1,500 times the normal level.
The disruption also affected the Singapore Institute of Technology and the Singapore University of Social Sciences. Microsoft confirmed on 13 November US time that services had fully recovered across Teams, Outlook, Copilot and other applications, ending an outage that crippled online communications for over 24 hours.
Microsoft's response
In a statement on 14 November, a Microsoft spokesperson apologised for the disruption, saying the company takes seriously the trust customers and partners place in its services. The spokesperson confirmed the incident was not related to a cyber attack or artificial intelligence agents.
Microsoft said the problem originated from an issue during an earlier network capacity upgrade that surfaced following a subsequent network change. The company said it would publish a full post-incident report once its internal review is complete.
