Specifying the registry information from Azure Active Directory for authentication with OAuth 2.0

Select the entry Microsoft Exchange under E-mail management.
Select OAuth 2.0 (Microsoft Office 365) under Exchange Web Services authentication method in the Connection settings perspective.
Enter the directory ID that you previously copied to the clipboard in Azure Active Directory under Office 365 Directory ID.
Enter the application ID that you previously copied to the clipboard in Azure Active Directory under Office 365 Application ID for d.ecs groupware.
Enter the client secret that you previously copied to the clipboard in Azure Active Directory under Office 365 API Access Key for Exchange Web Services.
