Microsoft outage runs into Friday, Outlook, 365 still hit

November 13, 2026 (MLN): Microsoft suffered a widespread global outage that began shortly before 1pm ET on Thursday and ran into Friday, disrupting Outlook, Teams and other Microsoft 365 services including SharePoint and Copilot.

Email and other tools were unavailable to users through much of the Asian business day and into early European hours, while external services linked to Outlook features such as Calendar also faced problems.

In an update just before 7:30am London time (2:30am ET) on Friday, the company warned that users might still be unable to connect to several Microsoft 365 services, including Outlook on web and desktop.

It gave no timeline for full restoration but reported positive results for server stability after applying a new patch fix to some of its infrastructure, CNBC reported.

Microsoft added that it was not aware of any malicious activity behind the incident and would treat it with urgency until full resolution.

It also promised a detailed report once the problem is mitigated, and added more computing capacity through virtual machines.

The company first blamed elevated load across multiple regions for the connectivity problems.

It later found that a number of servers had become unexpectedly unavailable, straining the remaining infrastructure, and that some servers were failing automated health checks.

At 4pm ET on Thursday, it validated an alternative service health check method that brought some affected servers back online and began applying the change more broadly.

Microsoft is also preparing automated recovery systems to continually detect and restart unresponsive servers.

Governments and businesses in Asia-Pacific and Europe monitored the situation as disruption spread.

Swiss luxury group Richemont delayed its Friday earnings slightly because of the outage, while electric truck maker Workhorse Group pushed its third-quarter results from Nov 12 to Nov 16, citing business disruptions.

Air India temporarily rerouted emails to keep receiving customer messages, adding that flight operations were unaffected.

Separately, Amazon Web Services and Google users also reported outages on Thursday.

Amazon said on X that its services were operating normally and that an unrelated disruption elsewhere on the internet was prompting inaccurate news reports, pointing users to its health dashboard.
