Microsoft 365 outage: How UAE businesses can protect themselves from cloud downtime

Résumé détaillé

Technology leaders say Microsoft disruption is a warning for UAE firms that have built their daily operations around one provider, with email, documents, sign-in and even AI tools going down together

A disruption to Microsoft 365 this week has prompted technology experts to warn UAE businesses that relying on a single cloud platform without a fallback plan carries a serious operational risk.

Microsoft has said its servers failed automated health checks and that it has found no sign of an attack. Andreas Hassellöf, CEO of Ombori, said that makes it a reliability event that “could happen to any large provider”.

Experts stressed that Microsoft 365 underpins far more than email. Hassellöf said it sits at the centre of communication, documents, sign-in and approvals, so applications that depend on it for access can stall too.

Morey Haber, Chief Security Advisor at BeyondTrust, said companies can lose Outlook, SharePoint, OneDrive and Teams at the same time. For UAE firms working across international time zones, even a few hours of downtime can disrupt transactions, customer engagement and decisions well beyond a single business day.

“My concern is not that Microsoft experienced an outage,” Haber said. His worry is that many organisations have built their entire productivity ecosystem around one provider “without adequately planning for an outage”.

Chris Miglino, CEO of Axe Compute, said the outage also took Copilot offline, halting AI-assisted drafting, summarising and document searches. That matters in the UAE, where Microsoft’s research put generative AI use at 73.3 per cent of the working-age population in the second quarter, the highest in its global rankings.

“The deeper the adoption, the larger the share of work that pauses,” Miglino said.

The experts agreed that healthcare and government are among the most vulnerable, though they differed on other sectors. Hassellöf said education is exposed because an outage hits many students and teachers at once, and real estate sees delays in documents, approvals and client communication.

They stressed that the key question is whether a company loses productivity tools or the ability to deliver an essential service.
