Microsoft says it has restored service to the remaining customers and regions affected by the global Microsoft 365 outage, ending a disruption that left Outlook, Teams, Copilot and other cloud services unavailable or unreliable for more than 24 hours.
In a Saturday update, the company said it had completed its work on the underlying issue and restored service to the remaining affected customers and regions. The announcement appeared on Microsoft’s official status account.
The outage began on November 12 and centered on Exchange Online, the cloud email and scheduling service behind Outlook. The initial global disruption also affected Teams and other Microsoft 365 features used by businesses and public agencies, while Australian government agencies reported problems with their Microsoft services.
Reuters reported that Downdetector logged more than 7.4 million user reports worldwide during the incident, with reports peaking at nearly 20,000 a minute. The figures count outage reports submitted by users, not a verified number of affected people or organizations.
Microsoft said the outage was a technical issue unrelated to cyber activity or AI agents. In an earlier explanation, the company traced it to a problem introduced during a network-capacity upgrade that surfaced after a later network change. Microsoft said it would publish a full post-incident report after its review. The explanation was posted through Microsoft 365 Status.
