MC1158908 - Support for Events from email in Outlook is changing—Schema.org markup required for reliable calendar extraction

Updated December 8, 2025: We have updated the content and timeline. Thank you for your patience. 

Introduction

Outlook’s Events from email feature helps users stay organized by automatically adding reservations such as flights, hotels, rental cars, and deliveries to their calendars.  To improve reliability and ensure this feature continues to work smoothly, we strongly encourage all providers to adopt Schema.org markup in their transactional emails. This change aligns with industry standards and improves accuracy, consistency, and long-term support.

Until now, Outlook has relied on legacy extraction to support this feature. However:

• Legacy extraction is fragile, and once templates fail, they cannot be fixed.
• We are receiving increasing reports of incorrect or missing events.
• It is technically impossible to make further improvements to the old stack.
• Without migration to Schema.org,By January 2026, the quality and reliability of eventold extraction stack will continue to degrade over time.no longer be supported.
