Understanding Dynamics 365 and Office 365 Admin Roles

Managing Dynamics 365 instances

If you run Microsoft Dynamics 365 (formerly Dynamics CRM) in the Microsoft cloud, you need to understand how your Dynamics instances relate to Office 365 and choose which of your administrators receives which roles and permissions to manage Dynamics 365.

In on premises deployments, your network administrator would create and delete user accounts.  The Dynamics 365 admin would then assign permissions to users in Dynamics 365.

This post explains three administrator roles:

  • Office 365 Global Administrator
  • Dynamics 365 System Administrator
  • Dynamics 365 Service Administrator

You may think that the Dynamics 365 system administrator would have power to do all the actions needed to manage Dynamics 365, but this is not the case. What's different in Microsoft cloud deployments is that licenses and user accounts are managed in Office 365 by an Office 365 Global Administrator.  This role is analogous to a network administrator for an on premises deployment.  The Global Administrator is the only role to create new user accounts and assign subscription licenses for Dynamics 365 (and other Office 365 apps such as Skype, Power BI and SharePoint).    The Global Administrator can also assign other admin roles, and is automatically a Dynamics 365 system administrator.  You can have more than one person assigned as Office 365 Global Administrator.

The Dynamics 365 system administrator may assign roles and permissions to the Dynamics 365 user within an instance of Dynamics 365.  The Dynamics 365 system administrator also controls all the settings in Dynamics 365.

In 2017, Microsoft introduced a new administrator role called Dynamics 365 Service Administrator to Office 365.  This is a customized administrator role with fewer permissions than the Global Administrator.  It may be configured at the app level.

The Dynamics 365 service administrator can manage Dynamics 365 instances, such as performing backup and restore, copy and reset actions.  These actions are often used to promote development instances to test or production.  

The service administrator may open and view support tickets with Microsoft and view the service dashboard and message center.  

Before you go live with Dynamics 365, be sure that your users, help desk and administrators understand their roles, how they can communicate, and when and how to get help from Microsoft.

Key Concepts for Microsoft Dynamics 365: Tenant, Instance, App and Solution

Updated 8/15/2022 To understand Microsoft Dynamics 365 (formerly Dynamics CRM) and Power Apps, you need to learn some new terms and concepts that may be a bit different from what you know from databases and solutions that are hosted on premises.  These concepts also apply to Power Apps.  The main difference is that with Power Apps you are not starting with a Microsoft app but more of a blank canvas for your custom apps.  This post introduces some key terms and how these concepts are important for planning your implementation. While Dynamics 365 is still available on premises, it is most commonly deployed on the Microsoft cloud.  This blog post discusses only cloud implementations. Microsoft has multiple clouds such as commercial and government community clouds in several countries. We start with a Microsoft tenant .  A tenant is the account you create in the Microsoft Online Services environment (such as Office 365) when you sign up for a subscription. A tenant contains uni
