Observed every November 12
On November 12, 2026, a global outage knocked Outlook email offline for millions of people. Work kept going anyway, through chats, calls, shared docs and plain conversation.

Outlook stops sending and receiving for users around the world. Outage trackers log more than 130,000 reports at the peak.
Teams, OneDrive and other services from the same provider are hit as well, so many teams lose their fallback at the same moment.
