 To configure and use Relationship Intelligence with Office 365 mail server, you need to create a new server connection in the Microsoft Azure Portal. The parameters that must be registered in the Microsoft Azure Portal are:

Server Tenant ID: This is the unique identifier of your Microsoft 365 tenant. You can find it in the Azure Active Directory admin center under Properties.

Certificate File: This is the public key certificate that you generate and upload to the Azure Active Directory admin center to authenticate your Dynamics 365 Sales app with Microsoft 365.

Certificate Key: This is the private key that corresponds to the certificate file. You need to enter it in the Sales Insights settings under Relationship insights > Analytics and Health.

These parameters are required to enable the exchange integration for relationship analytics, which allows Dynamics 365 Sales to collect and analyze email and meeting data from Microsoft 365. References = Configure relationship analytics and health, Overview of Relationship intelligence, Dynamics 365 Sales - Relationship intelligence
