Register the Application

You must register the application with Microsoft Azure Active Directory (Azure AD). Azure AD manages the connection between Office 365 with Exchange and the Exchange Mailbox. You use information that you generate in Azure AD to configure your the Exchange Mailbox.

Multiple azure apps are aid better performance and minimize throttling.

For example, you can add 5 apps for every Office 365 client that has 2500 mailboxes and additional app for every 1000 mailboxes.

When you perform this procedure, record the following values of the new application. You will use these values later when you configure your Commvault environment.

  • Application ID

  • Key value

  • Directory ID
