Microsoft 365 outage: you may get money off your bill if you use it for work, but you’ll have to ask Microsoft for it, as a server failure takes down Outlook, Teams and Exchange

AI-summarised brief · reviewed before publication

On November 12, Microsoft confirmed a major outage that knocked out most Microsoft 365 services, including Outlook, Teams, OneDrive, Copilot, Exchange Online, SharePoint Online and Defender XDR. The disruption began around 1:25 PM ET, with Microsoft attributing it to an unexpected loss of servers that overloaded the remaining infrastructure. The company paused deployments, freed memory, rerouted traffic and rebooted servers in an effort to restore service, but outages persisted for several hours. Customers with enterprise licenses may be eligible for service‑level‑agreement (SLA) credits, which are calculated based on the specific services affected, the duration of downtime and the number of user‑minutes impacted. Credits range from 25 % to 100 % of the affected service fees, depending on whether uptime falls below 99.9 %, 99 % or 95 %.

💡 Why It Matters

  • · Enterprises can recoup a portion of their subscription costs by claiming SLA credits, turning a costly downtime into a partial financial remedy.
