Microsoft Outlook and Teams global outage affecting Singapore users, Digi Mart USA News (Singapore): Microsoft Outlook suffered a major outage on Thursday (Nov 12), with tens of thousands of users, including those in Singapore, struggling to access their email as the company said it was working “aggressively” to reduce the impact.
Microsoft attributed the connectivity issues to “elevated load” on its infrastructure across multiple regions. The disruption also appeared to affect other Microsoft products.
Microsoft initially said it was investigating outage reports “in the Americas,” but later said it had “confirmed the issue may affect Microsoft 365 service connectivity for users in any region”.
Microsoft 365 is the company’s cloud-based subscription service that includes popular applications such as Outlook and Teams. According to outage tracker Downdetector, nearly 130,000 users reported issues with Outlook shortly after 1pm Eastern Time (6pm GMT).
Outage reports had since declined, with about 50,000 users reporting issues with Outlook as of 4.30pm Eastern Time.
Downdetector also recorded more than 38,000 user reports of problems with Microsoft 365 and about 4,500 reports of users having trouble accessing Teams.
In Singapore, the outage tracker recorded 250 reports for Microsoft Outlook at 7.05am on Friday, along with 152 reports for Microsoft 365. The Microsoft Outlook reports had more than doubled to 535 at around 7.55am. About 40 per cent of the reports were related to issues with the Microsoft Outlook app, while 25 per cent were tied to receiving messages.
Other reports were related to login issues.
Microsoft wrote on X: “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: “We’re aggressively pursuing all pathways to reduce impact.” It said it had paused all deployments, was moving additional traffic off the affected infrastructure, and was restarting affected servers to return them to service.
Microsoft said earlier in the day it had fixed a Teams disruption affecting users in North America and that the impact had been fully resolved. The company later said the issue may also affect Microsoft 365 service connectivity for users in other regions.
OpenAI said it was investigating an issue with Microsoft connectors in which new connections may be broken and tools are not working as expected. Anthropic said it had identified an issue with an upstream provider affecting its Microsoft 365 connector.
