A worldwide Microsoft 365 outage that began on Thursday 12 November 2026 stopped many people from sending or receiving Outlook email and disrupted Teams, OneDrive and Copilot. By 14 November Microsoft reported broad recovery and said the cause was a problem from an earlier network capacity upgrade, not a cyberattack or AI. Some users may still see delays; check Microsoft's official status page before changing anything on your device.

Status note: this article describes the outage that started on 12 November 2026. Microsoft reported broad recovery on 13–14 November. Always confirm the current state on Microsoft's own status page linked below.

What happened

From the afternoon of Thursday 12 November 2026 (US Eastern time, early 13 November in Pakistan), Microsoft 365 users around the world began reporting that Outlook would not load, send or receive email. Microsoft's own incident notice put the start at about 1:25 pm Eastern time. Monitoring site Downdetector recorded nearly 140,000 Outlook reports at the peak, and problems were reported in at least 74 countries.

Microsoft first said a large number of servers had become unexpectedly unavailable, overloading the rest. It later explained that the root cause was an issue introduced during an earlier network capacity upgrade that surfaced after a recent network change. The company said clearly that it was a technical failure, not a cyberattack and not related to AI, and apologised to customers.

Which services were affected

Outlook email and calendar (work, school and personal accounts)
Microsoft Teams (some users could still chat and join meetings)
OneDrive and access to some files
Copilot
Some admin and security tools for businesses

Recovery status

Microsoft rolled the fix out in stages. On 13 November it reported "encouraging recovery progress", first in North America and Europe, with Asia-Pacific following later. By 14 November it reported broad recovery and stability, with email queues "approaching normal levels", while still restoring service for remaining customers and regions. Microsoft also said delayed messages were being held and delivered, rather than lost.

How to check whether Outlook is down

Open Microsoft's service status page (status.cloud.microsoft). It shows whether Microsoft 365 or consumer services such as Outlook.com have a known problem.
If you use a work or school account, your IT admin can see detailed incident notes in the Microsoft 365 admin centre under Service health.
Try Outlook on the web (outlook.office.com or outlook.live.com). If the web version works, the problem is probably with the app or your device rather than Microsoft.
Try another internet connection, for example mobile data instead of Wi-Fi.

Wait until the status page shows the issue as resolved before changing your password; repeated failed logins during an outage can lock your account.
Sign out of Outlook completely, close it, and sign back in.
On a phone, update the Outlook app from the Play Store or App Store.
Clear the app cache on Android (Settings › Apps › Outlook › Storage › Clear cache). Do not choose Clear data unless you are sure your mail is stored on the server.
If you are asked to sign in again and again, remove and re-add the account in Outlook.

What to do about delayed or missing emails

Microsoft said email delayed by the outage would be delivered as its systems caught up. Give it time before resending important messages, because resending can create duplicates. If something urgent did not arrive, ask the sender to check their Sent folder and any "undeliverable" notice. Businesses should check message trace in the Exchange admin centre.

Should you reinstall or reset Outlook?

Usually no. During a Microsoft-side outage, reinstalling Office or resetting Windows does not help and can make things worse. Only troubleshoot your device once Microsoft's status page shows no active problem and Outlook on the web works but your app still does not.

Microsoft said an issue introduced during an earlier network capacity upgrade overloaded its infrastructure. It said it was not a cyberattack and not related to AI.
