Domains

The Domains section in MSPControl is used to manage the domains assigned to the current hosted organization. This page does not create brand-new domains from scratch. Instead, it allows administrators to allocate domains that were already added earlier in Account > Domains and make them available for use in the current hosted organization.

This separation is important because a domain may be available in the broader account scope but not every hosted organization needs to use it. The Domains page provides the control layer that lets administrators allocate only the domains that are actually required for the current hosted organization and its services.

Domains Overview

The Domains page displays the domains currently allocated to the hosted organization. These domains can then be used by services associated with that organization, such as email-related features, Office 365 integration, and other hosted-organization functions that depend on domain availability.

This page is especially useful in environments where multiple domains exist at the account level but only some of them should be available inside a particular hosted organization. By controlling allocation here, MSPControl helps keep the hosted organization clean and limited to only the domains it actually needs.

Domains List Page

The main Domains page displays the currently allocated domain names in a table. From this page, administrators can add another existing account-level domain to the hosted organization, mark a domain as the default one, open Entra ID Domain Service settings, and review usage or Office 365-related status for each domain.

Domains Page Actions

1. Add New Domain opens the allocation window where an already existing domain from Account > Domains can be assigned to the current hosted organization.
2. Set Default Domain marks the selected domain as the default domain for the hosted organization.
3. Entra ID Domain Service opens the Azure > Entra ID Domain Service page.
4. Column Visibility allows administrators to control which columns are displayed in the domain list.
5. Page Size Selector controls how many rows are shown in the table at one time.

These actions make the page both a domain-allocation view and a lightweight management center for hosted-organization domain usage.

Domains Table Columns

1. Domain Name shows the domain allocated to the hosted organization.
2. Default Domain shows whether the domain is currently marked as the default one.
3. DNS Enabled shows whether DNS-related functionality is enabled for the domain.
4. Office 365 shows the Office 365 status for the domain. In the example shown, the status is Managed.
5. Edit O365 provides the control for editing Office 365-related settings for the domain.
6. Actions shows row-level actions such as View Usage or a connected-state indicator such as Connected to o365.

At the bottom of the page, MSPControl also displays summary counters such as Total Domain Names Used and Total Entra ID Domains. These counters help administrators understand how many domains are currently allocated in the organization context.

Add Domain Name

When administrators click Add New Domain, MSPControl opens the Add Domain Name window. This window is used to allocate an existing domain to the current hosted organization.

This is not a domain-creation workflow. The domain must already exist in Account > Domains before it can be selected here. The purpose of this page is to make the domain available inside the current hosted organization only when it is actually needed.

Add Domain Name Fields

1. Domain Name allows the administrator to choose one of the domains that already exist at the account level and allocate it to the hosted organization.

This approach is useful because domains may support different services and not every hosted organization should automatically receive every available domain. By allocating domains here, administrators can keep service scope limited and intentional.

Add Domain Name Actions

1. Add Domain allocates the selected existing domain to the hosted organization.
2. Cancel closes the window without making changes.

Entra ID Domain Service

The Entra ID Domain Service button leads to the Azure > Entra ID Domain Service page. This means the Domains page is also connected to Azure-related domain service configuration and acts as a navigation point for administrators who need to move from hosted-organization domain allocation into Entra ID domain service management.

This is useful in hybrid or cloud-connected environments where domain setup and Azure directory services must be reviewed together.

Default Domain and Service Use

The ability to mark one domain as the Default Domain is important because many workflows depend on having one primary domain for the hosted organization. This may affect how new objects are created, how domain-related services behave, or which domain is used first when the platform needs a default choice.

Because domains may be used by different services, administrators should review carefully which domain is allocated and which one is set as default. The page is designed to make sure only required domains are available here rather than automatically exposing all account-level domains.

How Domains Fit into MSPControl

The Domains page sits between account-level domain preparation and hosted-organization service usage. First, domains are added in Account > Domains. Then, only the domains needed by a specific hosted organization are allocated here.

This separation gives administrators better control over scope and reduces accidental overexposure of domains to hosted organizations that do not need them. It also helps keep service configuration cleaner, because only relevant domains are available in the organization context.

Best Practices

• Add domains to Account > Domains first, then allocate only the required ones to the hosted organization through this page.
• Do not treat Add New Domain as a domain-creation feature. Use it as an allocation step for already existing account-level domains.
• Set the Default Domain carefully, because it can influence how hosted-organization services and object creation behave.
• Allocate only the domains the hosted organization actually needs, especially in environments where different tenants use different domain sets.
• Review the Office 365 and Edit O365 columns when domain behavior is tied to Microsoft 365 or Exchange-related services.
• Use View Usage to understand how a domain is being used before changing allocation or default-domain behavior.
• Use the Entra ID Domain Service button when domain allocation needs to be reviewed together with Azure directory domain service settings.
• Monitor the summary counters at the bottom of the page to keep track of allocated domain totals and Entra ID domain usage.
