Microsoft Offers 50% Service Credit for Outlook Outage, But Claims Required

Microsoft is offering service credits up to 50 percent of monthly fees to businesses affected by this week's Outlook outage, but customers must file claims manually by the end of December 2026. The outage, which began Thursday and lasted over 18 hours for some, disrupted Outlook and Microsoft 365 services like Teams. Credit amounts depend on subscription terms, outage duration, and affected user count, with calculations based on user-minutes rather than elapsed time. Credits apply only to specific affected services, not entire subscriptions, and exclude compensation for lost revenue or operational costs. Businesses should document the disruption and contact their Microsoft provider or support channel to submit claims.
