RE: Display list of contact and modify the list.
The core of Microsoft Dynamics 365 functionality is relationship management. It is designed to manage business-to-business (B2B) relationships—that is, relationships with other organizations and the contacts working at those organizations. Microsoft Dynamics 365 can also manage business-to-consumer (B2C) relationships, meaning relationships with individuals not associated with a specific organization.
Regardless of your industry or whether your organization is for-profit or non-profit, these relationships ought to be managed using the account and contact records in Dynamics 365. The name of these records can be changed, by a system customizer, to suit your needs.
