Microsoft’s suite of cloud‑based services, including Outlook, experienced a worldwide interruption that began on 12 November 2026 and continued into the following day. The outage affected users across multiple regions, halting access to email and other core productivity tools.
The details
The disruption was first noted on 12 November 2026 when users reported that Microsoft services stopped functioning. By the next day, 13 November 2026, the problem persisted, leaving Outlook and other widely used applications unavailable on a global scale. Outage‑monitoring platform DownDetector recorded a large volume of reports from individuals unable to reach Outlook, indicating a widespread impact. The incident coincided with a period when the UK government had issued warnings urging organisations to prepare for potential service interruptions, underscoring the significance of the outage for both private and public sectors.
Background
Microsoft is a multinational technology company that provides a range of software, cloud computing, and online services used by individuals, businesses, and governments worldwide. Outlook is a core component of Microsoft’s productivity suite, offering email, calendar, and contact management functions that are integrated with the company’s broader cloud infrastructure. When such services become inaccessible, users lose the ability to send and receive electronic communications, share files, and coordinate schedules, which can disrupt daily operations. DownDetector is an online service that aggregates user‑submitted reports of technical problems, allowing real‑time tracking of outages across various platforms.
What to watch
The facts do not specify any immediate remediation steps or a timeline for service restoration, leaving the duration of the outage and the technical cause open for further clarification. Observers will be looking for official statements from Microsoft regarding the root cause and any measures taken to prevent similar disruptions in the future.
Why it matters: A global outage of Microsoft’s core services highlights the vulnerability of digital communication infrastructure that underpins modern business and governmental operations.
