Microsoft today announced that the company is releasing Outlook REST APIs for Mail, Calendar, and Contacts support for Office 365 and Outlook.com. The company will rolling it out alongside the new upgrade for Outlook.com. Microsoft stated that apps will be able to use Outlook REST APIs to access users’ mailboxes, and allow developers to reach 400 million monthly active users:
We are excited to announce Outlook REST APIs for mail, calendar, and contacts now support both Office 365 & Outlook.com! This single REST API endpoint https://outlook.office.com/api combined with a new app registration portal and v2.0 app model announced by the Azure Active Directory team, makes it very easy to build a single app that can be used by both Office 365 and Outlook.com users.
As previously announced, we are upgrading Outlook.com users to a new Office 365-based infrastructure. As users are upgraded, apps can use Outlook REST APIs to access these users’ mailboxes. This new platform will enable developers to reach 400 million monthly active Outlook.com users, in addition to tens of millions of Office 365 users. If your app utilizes both REST APIs and our add-in platform, you are all set as we also support Outlook Add-ins for Office 365 and Outlook.com users.
