Microsoft Works to Restore Services After Outage Reports Span 74 Countries

Disruption reports involving Microsoft’s services spanned 74 countries and territories within about an hour, affecting banks, governments and courts as engineers worked Friday to restore Outlook, Teams and Copilot.

The outage began Thursday. Microsoft warned that mailbox access could fail and email delivery was delayed; core Teams functions remained available.

Microsoft described recovery as partial and said service traffic was returning gradually. The company had not given a timetable for full restoration. Microsoft said it had found no sign that an outside party caused the outage and that malicious activity was not to blame.

In the United States, engineers at the House of Representatives were working with Microsoft, while city governments around the country reported widespread email problems.

MSFT shares fell about 2% in premarket trading Friday and were on pace for their lowest close since Nov. 2 and their worst weekly performance since the week ended July 24.
