Thousands of people around the world were left struggling to access their emails and workplace applications after a widespread Microsoft outage disrupted several services, including Outlook, Teams and Copilot.

The disruption, which reportedly unfolded on Thursday, affected users across 74 countries and territories, highlighting how heavily businesses and individuals rely on Microsoft’s cloud-based services to keep their daily operations running.
For many users, the problems meant more than an inconvenient email interruption. With Outlook, Teams and other Microsoft 365 applications affected, the outage also disrupted communication and access to essential workplace tools.
While we’re working to mitigate impact, we’ve confirmed the issue may affect Microsoft 365 service connectivity for users in any region, more information will be provided in the Microsoft 365 admin center under EX1550543.

Microsoft outage spreads across multiple regions
Reports of problems reportedly began climbing rapidly, with outage-tracking platform Downdetector recording approximately 130 000 reports relating to Outlook in the United States shortly after 13:00 Eastern Time, equivalent to 20:00 in South Africa.
Users reported difficulties opening their inboxes, sending and receiving emails, while others experienced problems accessing Microsoft’s wider range of services. The disruption was not confined to the United States. Downdetector reported that Microsoft products were affected in 74 countries and territories, with outage reports emerging across the Americas, Europe, Asia and Africa.
Microsoft initially investigated reports affecting users in the Americas before confirming that the problem could extend to its global customer base. In updates shared on X, the company said the disruption was linked to elevated demand on parts of its infrastructure.
“We’ve determined a portion of infrastructure is experiencing elevated load across multiple regions, which is likely contributing to the connectivity errors.”
The company added that it was “aggressively pursuing all pathways to reduce impact.”

Outlook was not the only service affected
Although Outlook attracted the largest number of outage reports, several other Microsoft products were also affected. Users experienced difficulties with Teams, the company’s workplace communication platform, as well as Copilot, its artificial intelligence assistant.
Other Microsoft 365 services, including SharePoint Online, Exchange Online and Microsoft Defender XDR, were also among the platforms affected by the disruption. The reported problems extended beyond Microsoft’s own products, with some services from AI companies Anthropic and OpenAI also reportedly experiencing difficulties linked to their reliance on Microsoft’s infrastructure.
The incident once again illustrated how disruptions affecting major cloud infrastructure providers can have consequences across multiple technology platforms.

Microsoft works to restore services
Microsoft spent much of Thursday attempting to stabilise its infrastructure and restore access for affected users. The company said some servers were experiencing problems and failing automatic health checks, placing additional pressure on infrastructure that remained operational.
Its recovery measures included pausing deployments, redirecting traffic away from affected infrastructure and restarting servers that had become unavailable. Microsoft also tested configuration changes intended to distribute traffic more evenly across its systems.
At one stage, the company reported signs of improvement, although a full recovery remained gradual. “We’re working to safely return them to service,” Microsoft said in an update about its efforts to restore affected infrastructure.
The company also warned that users might not regain access simultaneously, as applications and devices reconnected while capacity was brought back online. Downdetector reports eventually began declining, although tens of thousands of users were still reporting Outlook problems several hours after the disruption began.
Another reminder of the risks of cloud dependence
The outage comes just weeks after another significant Microsoft disruption involving its Azure cloud platform, which also affected productivity services and businesses. For companies that use Microsoft 365 as their primary workplace environment, incidents like these can bring everyday operations to a standstill.
Email, document sharing, online meetings and internal communication are often managed through interconnected cloud services. When part of that infrastructure experiences problems, the impact can spread well beyond the original platform.
For South African businesses and employees using Microsoft products, the disruption is another reminder of how dependent modern workplaces have become on international technology infrastructure.
While Microsoft worked to restore normal operations, Thursday’s incident showed that even widely used global platforms are not immune to outages, and that a problem affecting one provider can quickly become a much wider disruption.
