Outlook email hasn't worked since this morning

Outlook/Outlook.com is experiencing a broader Microsoft 365 outage, but Microsoft has not published a confirmed time for full restoration.

Some affected servers had returned to a stable state by late November 12, but service remained intermittent during recovery.^1^ Microsoft is working to restore the impacted systems and prevent additional servers from being affected.^2^

Check Microsoft’s Service Health Status site for the latest recovery update and any official ETA. Microsoft Support directs Outlook.com users there for current access problems.^3^

Until that page reports recovery, retry periodically rather than changing your password, reinstalling Outlook, or altering account settings. After Microsoft marks the incident resolved, if your email still fails, test Outlook.com in a browser; a continuing account-specific problem can then be investigated separately.
