Microsoft Outage Slows Work in North America
Elevated infrastructure load caused connectivity errors affecting Outlook and Microsoft 365 services on Thursday.

Microsoft faced a widespread service disruption on Thursday that interrupted work routines for employees across Canada and the United States. The failure primarily targeted Microsoft Outlook, though connectivity issues also rippled through the broader Microsoft 365 suite and the Copilot assistant. Users in both countries reported difficulties accessing core productivity tools during standard business hours, creating a digital pause in the daily workflow.
The incident began to gain momentum on Thursday afternoon. By 1:30 p.m. ET, the outage tracker Downdetector logged nearly 140,000 reports of problems specifically related to Outlook. The issue persisted into the late afternoon, with more than 50,000 reports still active as of 4:52 p.m. The company’s service incidents team confirmed it was actively investigating the cause of the disruption.
Microsoft attributed the technical failure to specific infrastructure strain. The company stated online that a portion of its infrastructure was experiencing elevated load across multiple regions. This high demand was likely contributing to the connectivity errors users encountered. The impact extended beyond email, affecting other applications within the Microsoft 365 subscription, including Word, Excel, Teams, and OneDrive.
Other major technology platforms also recorded outages during the same timeframe. As of 5:15 p.m., Downdetector noted more than 500 reported issues with Amazon Web Services in Canada and the U.S. Gmail users reported a higher volume of problems, with more than 1,000 complaints logged by the same hour. These concurrent disruptions suggest a wider pattern of network instability in the region that day.
Social media reactions from affected users ranged from frustration to ironic relief. Some individuals expressed disappointment over the loss of productivity tools, while others appreciated the unexpected break from digital demands. One user wrote, "Take your time. The peace and quiet is nice LOL." Another suggested the company delay the repair, posting, "Please leave Outlook down till Friday 5 pm :)".
The incident remains the focus of Microsoft’s technical teams as they work to stabilize the affected regions. The company continues to monitor the elevated load on its infrastructure while users await a full restoration of service.
