Microsoft resolves global outage
Microsoft has successfully resolved the global service disruption that lasted for more than 36 hours. Now access to Outlook, Teams, Copilot and other Microsoft 365 services has been restored. The company said on Saturday, November 14 that the technical problem has been resolved, bringing relief to millions of users who were unable to use their work-related devices, email and other services. The disruption spread across more than 70 countries, affecting businesses, government institutions and ordinary users. Microsoft said customers using Outlook, Teams and Copilot for now should not have any problems, although the company is monitoring its infrastructure and email backlog. The company has apologized for the disruption and promised to provide a detailed report detailing the cause of the problem.
Cause and effect of blockage
The issue began on Thursday, November 12, when users reported difficulties accessing Exchange Online mailboxes. The disruption soon spread to Outlook, Teams, Copilot, SharePoint, Planner, To Do, and other Microsoft 365 services. While key messaging and online meeting features in Teams continued to function normally, features like calendars and meeting scheduling were affected. Copilot users also faced difficulties accessing work-related information. Microsoft explained that the issue was a technical issue related to an upgrade in network capacity, and was not caused by a cyber attack or AI agent.
Widespread impact of disruption
The impact of this disruption was not limited to email. Companies faced difficulties interacting with customers, finding research materials, and conducting daily operations. There were also disruptions in the functioning of government agencies and public institutions in many countries. In India, IndiGo reported that their email support services have been affected, causing them to have difficulty receiving customer emails. Air India said there has been no impact on their flight operations and they have diverted email traffic to alternative routes to continue interacting with customers. The outage also impacted AI companies, as OpenAI and Anthropic faced issues with their 'Microsoft 365 connectors'.
Microsoft's apology and future plans
Microsoft said it restored services gradually and checked stability at every step. The company has extended its email timeout window to 48 hours to protect against delayed messages while processing the backlog. Microsoft said it deeply regrets the inconvenience caused to customers and partners by this incident. The company also said it would continue to monitor its systems and email queues. A detailed report about the incident is expected after the investigation is completed.
