Outlook REST API

The Outlook REST API is a Microsoft Graph-based API that provides programmatic access to Outlook.com and Office 365 mail, calendar, contacts, and tasks data. It allows developers to integrate Outlook functionality into applications, enabling operations like sending emails, managing calendars, and accessing user contacts. The API uses RESTful principles and OAuth 2.0 for authentication, making it suitable for web, mobile, and desktop applications.

Also known as: Microsoft Graph Outlook API, Outlook API, Office 365 REST API, MS Graph Mail API, Outlook.com API

Why learn Outlook REST API?

Developers should learn the Outlook REST API when building applications that need to interact with Outlook or Office 365 data, such as email clients, scheduling tools, or CRM integrations. It is particularly useful for scenarios like automating email workflows, syncing calendar events across platforms, or accessing user contacts for business applications. Use it when you require secure, scalable access to Microsoft's email and productivity services without relying on older protocols like Exchange Web Services.
