Starting January 31, 2026, Microsoft Outlook is updating how it adds events—like flight bookings, hotel reservations, and package deliveries—from your email directly to your calendar.
What’s Changing?
Outlook has traditionally used a behind-the-scenes method to detect and add events from emails. But that system is becoming unreliable and will be retired. Going forward, Outlook will only support emails that use a modern, standardized format called Schema.org markup to extract event details.
If you rely on Outlook to automatically add travel plans or deliveries to your calendar, this change could affect you. After January 2026:
- Emails from organizations that don’t use Schema.org won’t create calendar events.
- Emails that do use Schema.org markup will continue to work as expected.
If you notice events missing from your calendar, you can check with the sender (like an airline or hotel) to see if they support Schema.org or if they are willing to adopt it so their emails continue to work with Outlook.
