A significant outage on Microsoft platforms, including Outlook and Teams, left nearly 130,000 users unable to access or send emails and experience connectivity issues, as Microsoft works to restore services.
- Nearly 130,000 outage reports on Downdetector for Outlook issues
- Teams and Microsoft 365 services also impacted by server outages
- Microsoft working on fixes and alternative recovery methods
What happened
On Thursday, Microsoft experienced a widespread outage impacting its email service Outlook, workplace messaging app Teams, and the broader Microsoft 365 suite. Over 130,000 users reported difficulties accessing Outlook around 1 pm IST, citing problems with sending, receiving, and loading emails. Additional issues affected Teams users and the AI assistant Copilot, with reports of connectivity failures and service disruptions.
Microsoft acknowledged the incident, highlighting that parts of its infrastructure were under elevated load which caused multiple Exchange Online servers to become unexpectedly unavailable. This failure was linked to automated health checks that removed servers from operation prematurely, resulting in degraded service performance across regions including India and the Americas.
Why it matters
Microsoft Outlook and Teams are critical communication and collaboration tools for millions of users in India, especially businesses relying on Microsoft 365 to operate efficiently. Disruptions to email and workplace messaging can significantly impact productivity, delay business workflows, and create operational challenges for enterprises and individual users alike.
Given the reliance on cloud-based services for daily functions, this outage underscores the risks of centralized infrastructure failures and the importance of resilient server management. The event also highlights ongoing challenges cloud providers face in maintaining seamless, high-availability service delivery in the face of unexpected technical faults.
What to watch next
Microsoft has already begun rolling out a fix by deploying alternative automated health checks to bring the affected servers back online. Monitoring how quickly and effectively this remedial action restores full service functionality will be key to gauging the impact duration and severity for users.
Further updates are expected from Microsoft regarding the root cause analysis and any long-term infrastructure improvements planned to prevent similar outages. Users and IT administrators in India and other affected regions should remain alert to ongoing status broadcasts and prepare contingency measures for critical communication needs.
