Introduction

Both OnPremise Exchange server and Office 365 Exchange admin Center uses a large set of predefined permissions, those can be used to grant permissions to your administrators and users instantly. Here the permissions features are used to set up role-based permissions for your Exchange server new organization up and running quickly.

In Exchange Server, the permissions that you grant to administrators and users are based on management roles. A role defines the set of tasks that an administrator or user can perform. When a role is assigned to an administrator or user, that person is granted the permissions provided by the role. Roles give permissions to perform tasks to administrators and users by making cmdlets available to those who are assigned the roles.

In this blog, we are detailing two types of roles, Administrative roles and End-user roles & Role groups & role assignment policies and Outlook WebApp Policies

  • Administrative roles: These roles contain permissions that can be assigned to administrators or specialist users using role groups that manage a part of the Exchange organization, such as recipients, servers, or databases.
  • End-user roles: These roles, assigned using role assignment policies, enable users to manage aspects of their own mailbox and distribution groups that they own. End-user roles begin with the prefix My.

Role groups and role assignment policies

  • Roles grant permissions to perform tasks in Exchange Server, but you need an easy way to assign them to administrators and users. Exchange Server provides you with the following to help you do that:
  • Role groups: Role groups enable you to grant permissions to administrators and specialist users.
    Role assignment policies: Role assignment policies enable you to grant permission to end users to change settings on their own mailbox or distribution groups that they own.
