Delayed emails, inaccessible Outlook inboxes and disrupted calendars: the global Microsoft 365 outage that began on 12 November has affected businesses and public organisations worldwide. Services are recovering, but the latest reports reviewed still provide no confirmed timeline for full restoration.

📧 What is affected? The disruption centres on Exchange Online, with knock-on effects on features that rely on email and calendars. Teams chats and calls may therefore work while meeting scheduling fails. Copilot has also experienced problems, with the impact varying between services and users.

🔧 What caused it? According to Microsoft’s explanation, reported by Sky News, a network gateway upgrade introduced a dormant bug several months ago. A subsequent network change triggered it, causing cascading failures. Microsoft says it has addressed the underlying issue and is gradually restoring services while checking stability and clearing accumulated workloads. The company says the incident was unrelated to cyberattacks or AI agents.

⏳ What remains unclear? Full recovery still needs confirmation, and Microsoft has promised a detailed post-incident report once its review is complete. Meanwhile, regaining access to Outlook does not necessarily mean every delayed email has reached your inbox.
