A Microsoft announced today that there is a widespread recovery of Microsoft 365 services affected by the global failure, lamented the incident and explained the problem with an update of network capacity, discarding a cyber attack.
“ Given the scale of demand, we gradually restore services by checking stability at each stage. Although this process took longer, it helped to ensure a stable restoration”, he assured, in a message published on social network X, in which he lamented the incident.
The US technology ensures that there is “a widespread recovery” and that there is “stability in all” services of the multinational.
“ The incident resulted in a failure during a previous update of network capacity, which was manifested following a recent change in the network. We solved the underlying problem and continued to restore the service to other customers and regions,” he explained, ensuring that it was “a technical problem not related to cybersecurity.”.
The company promises to provide “a full report as soon as the analysis of the incident is completed.
“ We deeply regret the inconveniences this incident has caused to our customers and partners. We are aware of the trust they place in our services and take this responsibility very seriously”, he said.
The global failure began on Microsoft 365 late in the afternoon of November 12 and left no access to Outlook, Teams, SharePoint, Copilot and Defend users from dozens of countries.
The Executive Vice President of Copilot, Microsoft Agents and Platforms, Charles Lamanna, had already confirmed, before this statement, that “no evidence” of malicious activity.
More than 70 countries, including Portugal, were affected by the failure.
The source of the crisis lies in a failure of Exchange Online, the cloud email engine of the technology company, a failure that has spread in cascade to all services that depend on Exchange to consult mailboxes, calendars, permissions or shared files.
According to Microsoft's official incidence report, the impact extended to about twenty essential applications, so users faced blockages in access to Outlook (on the web, desktop and mobile) and delays in email delivery.
