A massive global service disruption struck Microsoft on Thursday, November 12, 2026, and persisted into Friday, November 13, leaving millions of enterprise, government, and individual users worldwide including the Philippine judiciary unable to access core cloud productivity applications such as Outlook, Microsoft Teams, and Microsoft Copilot.
At the peak of the disruption, outage-tracking platform Downdetector logged nearly 130,000 problem reports for Outlook alone across 74 countries and territories, creating severe communication bottlenecks across North America, Europe, Australia, and the Asia-Pacific region.
In the Philippines, where connectivity issues began manifesting around 1:00 AM PHT on Friday, November 13, the Supreme Court issued an official public advisory confirming that the outage severely affected the judiciary’s digital infrastructure.
The High Court announced that the disruption directly hit Philippine Judiciary 365 (PJ365), its core enterprise workspace platform, including Microsoft Outlook. Because of the platform downtime, the Supreme Court warned litigants, legal practitioners, and the general public to expect delays in email responses and official electronic transactions.
“The Supreme Court informs the public that the ongoing worldwide Microsoft 365 service outage has affected the Philippine Judiciary 365 (PJ365), including Microsoft Outlook. During this period, responses to emails and other transactions may be delayed,” the Supreme Court stated in its November 13 advisory.
The High Court added that its technical teams are coordinating closely with Microsoft to restore all affected PJ365 services as quickly as possible and thanked the public for its patience during the temporary downtime. Local private enterprises and universities operating on Microsoft 365 infrastructure across Metro Manila and regional hubs also reported stalled email queues and calendar sync failures throughout Friday morning.
According to official status notices published under incident references EX1550543 and MO1550821 in the Microsoft 365 admin center, the outage primarily crippled services tied to Exchange Online:
Microsoft Outlook and Exchange Online users across desktop, web, and mobile clients were unable to load inboxes, send or receive messages, or synchronize calendar entries.
While core chat functions and active video calls on Microsoft Teams largely stabilized following an earlier separate incident (TM1550488), users experienced ongoing failures when scheduling meetings and initiating new group chats due to underlying Exchange dependencies.
Connectivity errors and elevated latency also degraded access to Microsoft SharePoint Online, OneDrive, and the AI assistant Copilot 365 across multiple geographic regions.
In technical status updates shared via official channels, Microsoft engineers revealed that the widespread outage stemmed from internal infrastructure overload rather than an external security breach.
Investigators determined that a server component responsible for processing automated server health checks and establishing secure connections became overwhelmed, causing affected servers to drop offline unexpectedly. As unavailable machines dropped from the network, remaining infrastructure absorbed severe load strain. Initial configuration adjustments aimed at redistributing traffic and restarting affected servers failed to provide immediate relief as restored servers repeatedly stalled under sustained connection surges.
Microsoft executive Charles Lamanna confirmed that there is no indication of a cyberattack or malicious intrusion behind the service degradation. Australian Home Affairs and Cyber Security Minister Tony Burke similarly noted that government officials assessed the incident as a software or configuration failure rather than a hostile cyber event.
Across the broader Asia-Pacific region, public agencies and corporations were forced to enact business continuity workarounds on Friday morning. Japan’s Deputy Chief Cabinet Secretary Masanao Ozaki confirmed that the outage disrupted government IT ministries in Tokyo, forcing civil servants to rely on printed physical documents, while courts, schools, and police departments across Australia transitioned to backup communication channels.
Cybersecurity authorities across affected territories have issued urgent warnings advising government personnel and corporate employees to remain vigilant against opportunistic phishing campaigns and fraudulent IT support scams attempting to exploit the downtime by soliciting login credentials.
Microsoft stated that its engineering teams are “aggressively pursuing all pathways” to restore full server capacity and pledged to publish a comprehensive post-incident root-cause report once global services fully stabilize.
