Microsoft Outage Spans 70+ Countries for More Than 15 Hours

By Priya Raman

Microsoft’s Friday updates and DownDetector reporting described an outage lasting more than 15 hours across more than 70 countries, with Outlook, Teams and Copilot still experiencing problems.

The failure extended across cloud-dependent products, reaching email, messaging and the Copilot assistant.

DownDetector, the online service monitor, had recorded 2,441 user reports about difficulty accessing Microsoft services at about 7:20 a.m. Brasília time on Friday. It said the volume of failure reports peaked at 3 p.m.

Microsoft had not announced a full restoration for Outlook by Friday. It said it was still working to normalize the platforms and acknowledged that its first response had not produced the expected result.

Microsoft initially had not identified the cause. It later attributed the interruption to an “elevated load” on its infrastructure, which produced connectivity errors across different regions.

In a company statement, Microsoft said: “At the moment, we have no knowledge of any malicious activity causing this incident. We will continue handling the case with urgency and priority until its full resolution.”

The company’s account on X, formerly Twitter, wrote: “Although we are working to mitigate the impact, we confirm that the problem may affect Microsoft 365 service connectivity for users in any region.”

On Thursday, Microsoft wrote on X: “We are monitoring the state of the changes applied to improve operation and confirm that they are not working as expected.”

The company added: “We are identifying alternative lines of action that can be implemented to increase capacity in the face of persistent imbalances in traffic management.” Microsoft did not say when it expected to restore the services fully.

A map published by Microsoft on X showed reports across the Americas and in regions of Europe, Asia and Africa.

The report said users in several sectors, including government agencies, had difficulty accessing email and maintaining communications.

New Zealand’s Ministry of Foreign Affairs said its “ability to receive emails was affected by the global Microsoft outage.” It added: “This also affects all embassies, consulates and representation offices of New Zealand around the world.”

What does the outage change for Microsoft 365 users?

For marketing and communications teams, the immediate change is operational: email, messaging and Copilot cannot be assumed to work reliably. Microsoft’s warning applied to users in any region, and the company had announced no full-restoration time. That makes service continuity, rather than individual account troubleshooting, the immediate test for organizations using the affected Microsoft 365 services.

Related coverage in the report described investors turning to WhatsApp and even fax to close stock-exchange business. Social media users also posted jokes about leaving Outlook behind for the week.

Microsoft’s next test is whether added capacity removes the connectivity errors across regions; until it confirms full restoration, Outlook, Teams and Copilot remain operationally unresolved, with no evidence of malicious activity and no recovery deadline on record.
