Microsoft's worst outage of 2026 hits industries worldwide, some customers seek fee compensation
IT Home, November 15 news: Microsoft's recent large-scale global service disruption lasted nearly a day, affecting not only its own services such as Outlook, Exchange, and SharePoint, but also other related platforms. Now, some affected customers are seeking service fee compensation from Microsoft, demanding that the company bear corresponding responsibility for the losses caused by this outage.
According to a Neowin report, many customers are currently gathered in a post on the Reddit forum r/msp, demanding that Microsoft pay a corresponding economic price for this service failure and calling on affected customers to submit Service Level Agreement (SLA) compensation claims. Such customers should submit the relevant incident numbers, customer tenant GUIDs, and materials proving the service interruption through their own corporate domains to the Microsoft Partner Center.
Refer to the incident numbers published by Microsoft. Among them, EX1550543 corresponds to an Exchange Online service failure, mainly affecting Outlook mailbox access and email sending and receiving; MO1550821 involves a broader range of Microsoft 365 service anomalies, including Teams, SharePoint, Defender XDR, Intune, Planner, To Do, Power BI, and Universal Print, among others.
However, obtaining Microsoft's approval is not easy. According to Microsoft's official documentation, the SLA service credit amount depends on the specific affected service and the duration of the outage. This means that even if a customer purchased a Microsoft 365 subscription covering multiple services, they can only apply for fee credits for service interruptions that actually occurred and meet the compensation conditions, and cannot calculate the compensation amount based on the entire subscription package.
Microsoft also explicitly stated that approved credit amounts will be reflected in the service provider's next bill and reconciliation data. For non-Azure services such as Microsoft 365, claims must be submitted within one month after the end of the billing month in which the outage occurred. Based on the timing of this outage, eligible service providers need to complete their claims by December 31, 2026 at the latest.
