Microsoft Faces Major Service Outages: Here's What to Know

On Thursday, reports emerged of significant outages affecting multiple Microsoft services, including Outlook, Teams, and Copilot. This incident has raised concerns among users who rely heavily on these applications for their daily tasks.

Scope of the Outage

By mid-afternoon, users reported a staggering nearly 83,000 complaints specific to Outlook on Downdetector. Though the numbers decreased somewhat to around 75,000 by 2:38 p.m., Teams also saw its reports drop to under 26,000, while Copilot registered fewer than 2,000 outages.

Microsoft's Initial Response

Shortly after the outage became apparent at around 10:40 a.m. ET, Microsoft acknowledged the situation through a social media post, stating they were aware of the issues. However, despite an update around noon claiming the problems were resolved, many users continued to face difficulties reported as late as 1:43 p.m. ET, affecting Teams, Outlook, and OneDrive.

Status Page and User Experiences

Compounding the confusion, Microsoft's service status page was also unresponsive for a time. Users were unable to access this resource until about 3:05 p.m. ET, leaving many without timely updates on the outage's status.

Experiences varied among users, as illustrated by an attorney from a law firm. At 2 p.m. ET, she reported issues with sending and receiving emails, although she could still perform searches in her inbox. Her firm indicated that this outage was impacting users on a global scale.

Continued Efforts to Restore Services

By 2:31 p.m. ET, Microsoft had paused all ongoing deployments as part of their response to the crisis. They clarified that the root cause of the outage was an unexpected number of servers being offline, not an increase in user traffic. The company is actively working to restore these servers safely to full functionality.

For administrators looking for updates on the issue, they can check incident codes EX1550543 and MO1550821 in the Microsoft 365 admin center. If access to the admin center is unavailable, users can visit http://status.cloud.microsoft for further information.

This story is evolving, and Microsoft has committed to providing more updates as they continue troubleshooting the situation. In the meantime, users are encouraged to remain patient as the team works diligently to resolve the ongoing problems.
