Microsoft Outage Triggers Cascading Financial Risks for Global Businesses

A continuing outage affecting Microsoft’s collaboration tools is expected to have a ‘cascading’ effect on businesses, with financial losses mounting as the disruption persists, according to an industry expert.

The interruption, which began on Thursday, impacted Microsoft 365 tools including Exchange Online and Outlook, with Teams, SharePoint Online, and Copilot also likely affected. While Microsoft is working on a resolution, the company has not yet disclosed the specific cause of the failure.

‘The ongoing outage of Microsoft’s collaboration tools, especially emails and scheduling, will not only impact communications, but also have a cascading impact on decision-making, revenue and service delivery,’ said Saurabh Verma, vice president, ICT growth advisory at consultancy Frost & Sullivan. He noted that revenue loss increases with every passing minute because millions of organizations across both critical and non-critical sectors are deeply integrated with the MS 365 suite.

According to Downdetector, which monitors internet disruptions, reports of the outage reached 74 countries and territories within one hour on November 12. Mr Verma added that the outage may also affect software as a service (SaaS) tools that utilize Microsoft’s 365 application programming interface (APIs).

‘With MS having a significant market share in collab tools, there is no escaping and second solution to it. No product in today’s age and time is immune to such outages,’ Verma added.

Such technology disruptions have become more frequent as digital usage grows. In October last year, the Microsoft Azure portal went down, affecting hundreds of thousands of users. This occurred in the same month as a 15-hour outage of Amazon Web Services, which disrupted various AWS-hosted services. Additionally, in June this year, several platforms including X, Zoom, Reddit, Canva, Amazon Web Services, Microsoft Teams, Fortnite, and Discord experienced significant disruptions.
