Outlook API reference documentation
The Outlook REST APIs are a part of Microsoft Graph. Microsoft recommends using Microsoft Graph to access Outlook mail, calendar, and contacts. You should use the Outlook API endpoints directly (via
https://outlook.office.com/api) only if you require a feature that is not available on the Graph endpoints.
For more information about the differences between Graph and the Outlook endpoints, see Compare Microsoft Graph and Outlook endpoints.
The following APIs are released and ready for production use in both the Graph and Outlook endpoints.
- Mail API

The following APIs are released and ready for production in the Outlook endpoint, but are in preview status in the Graph endpoint.
