Register the Application

Register the Exchange Online app with Microsoft Azure Active Directory (AD).

When you finish registering the app, record the Application ID and Directory ID. When you finish creating the client secret, record it. You will need to enter these values when you add an Exchange Online app.

To improve performance and to minimize throttling, you can register multiple apps. For example, for an Exchange Online app that has 2,500 mailboxes, register 5 apps. Every time an additional 1,000 mailboxes are added, register 1 additional app.
