Exchange offers a range of policies which can be applied to Exchange users to:
Typically, Exchange policy settings must be managed using PowerShell cmdlets and the various Microsoft tools such as the Office 365 portal, the Office 365 Admin Center, and the Exchange Admin Center.
With the Policy Management for Exchange Online module, you can manage policies through an intuitive user interface. Policies can be applied in bulk to target users and groups and the module automatically detects group changes. The application of policies can be scheduled in order to maintain the correct Exchange Online settings across the organization.
On Demand is a cloud based management platform that provides access to multiple Quest Software tools for Microsoft product management through a unified interface. Cloud based is a term that refers to applications, services or resources made available to users on demand via the Internet. Quest On Demand is a Software as a Service (SaaS) application where application software is hosted in the cloud and made available to users through quest-on-demand.com.
On Demand management is based on the concepts of organizations, modules, and Azure Active Directory (AD) tenants. When you sign up for the On Demand service, you create an organization. The organization can subscribe to modules. Organization administrators can use the tools provided by the modules to perform administrative actions on Azure AD tenants.
Each management tool is referred to as a module. Currently, the following modules are available:
On Demand Global Settings refers to management tools and configuration settings that apply to all On Demand modules. This includes tenant management tasks and downloading audit logs.
On Demand administration is based on organizations. When a user signs up for On Demand, an organization is created.
You can add users to an organization. To add a user, click Settings in the navigation panel on the left and then click Permissions.
Microsoft Azure also uses the concept of an organization. An Azure Active Directory (Azure AD) tenant is representative of an organization. It is a dedicated instance of the Azure AD service that an organization receives and owns when it signs up for a Microsoft cloud service such as Azure, Microsoft Intune, or Office 365. Each Azure AD tenant is distinct and separate from other Azure AD tenants.
A tenant houses the users in a company and the information about them - their passwords, user profile data, permissions, and so on. It also contains groups, applications, and other information pertaining to an organization and its security. For more information see this Microsoft help page.
Before you can manage Exchange Online policies, you must select an Azure Active Directory tenant. See the following topics:
Policy management actions are applied to a single tenant. Select Tenant in the navigation panel on the left. The Tenant page displays a list of tenants that have been added to an organization. If the page is empty, you must add a tenant.
To add a tenant, click Add tenant. For more information, click the help icon on the Tenant page or see Tenant management in the On Demand Global Settings User Guide.
Caution: Adding a tenant to multiple organizations.
Adding the same tenant to multiple organizations can result in conflicting application of polices and settings. When using multiple organizations to manage a tenant, the organization administrators must coordinate their management activities.
