Posted November 13, 2026, last updated November 13, 2026
Microsoft says the Outlook, Teams and Microsoft 365 outage is being fixed and most services are recovering, though some users may still see intermittent problems. Delayed email is being held for up to 48 hours, so you do not need to take any action.

- Update – Nov 13, 2:23 PM PST Secondary sources add a Friday timeline detail (returned servers failed again under traffic) and a report that Microsoft's recent fixes fell short; no new Microsoft advisory for MO1550821 has appeared.
- Update – Nov 13, 1:21 PM PST New items: Microsoft's status posts now point admins to MO1550821 as well as EX1550543, a post names an overwhelmed core process as the capacity problem, and a mirror of Microsoft's status shows the next update due around 5 PM on November 14.
- Update – Nov 13, 12:20 PM PST Microsoft has publicly apologized and said there is no indication of a cyberattack, and a CNN-cited estimate puts the outage's cost above $7 billion; no fix is declared and no second MO1550821 advisory has appeared.
- Update – Nov 13, 11:19 AM PST Microsoft has attributed the incident to an earlier network capacity upgrade and says broad recovery is under way, but no fix is declared and no second MO1550821 advisory has appeared.
