On November 12, a significant technical failure affecting Microsoft's Outlook, Teams, and Copilot AI services was reported to be resolving the following day. The outage was attributed to high load on Microsoft 365 infrastructure, impacting users worldwide including in the Americas, Japan, and Europe.
Microsoft confirmed 'encouraging progress' in Europe, noting that email distribution performance was improving on a growing share of the affected Microsoft 365 infrastructure. The company stated, "Nous constatons des progrès encourageants en Europe, avec une disponibilité des services et des performances de distribution des e-mails qui s’améliorent sur une part croissante de l’infrastructure Microsoft 365 affectée"
Microsoft reported that the situation in North America was also improving, while La situation au Japon reste relativement stable. Some users may still experience intermittent issues during the recovery process, as noted by Microsoft: "Certains utilisateurs peuvent encore rencontrer des problèmes intermittents pendant la poursuite des opérations de rétablissement"
The incident echoes a previous major global disruption in July 2024, when a CrowdStrike software update had paralyzed airports and hospitals.
