In the MS-203 Microsoft 365 Messaging exam, a key area that candidates need to master is maintaining and expanding configurations using the Hybrid Configuration Wizard (HCW).
This is pivotal for managing the Hybrid Deployment of Microsoft 365 Exchange Online and on-premises Exchange Server. The wizard is a potent tool and a hallmark of Exchange Server’s functionality, ensuring organizations have a seamless hybrid environment.
Understanding the Hybrid Configuration Wizard
The HCW is a crucial tool integrated within the Microsoft Exchange Server that helps in configuring a Hybrid Deployment. When first setting up a hybrid deployment, the HCW creates a HybridConfiguration object in your on-premises Active Directory. This object stores the hybrid configuration information for the hybrid-enabled Active Directory forest. It streamlines the set-up process by guiding the user through the necessary steps which include:
- Configuring hybrid features such as free/busy calendar sharing, mail routing, and mailbox migrations.
- Facilitating the secure mail routing between on-premises and Exchange Online organizations
- Assuring secure communication between the on-premises hybrid server and Microsoft 365/Office 365
Maintaining and Expanding Configurations
The job does not end once your hybrid setup is initially configured via the Hybrid Configuration Wizard; regular maintenance and possible expansion may be required according to the business needs.
Maintenance: After initial setup, it’s recommended to rerun the HCW whenever changes are made to the hybrid features. This makes sure that the Hybrid Configuration object in your on-premises Active Directory is updated.
For example, if you were specifically modifying your organization’s mail routing services, you would:
- Launch the HCW
- Navigate through the wizard until you reach the Hybrid Domains screen
- Adjust the routing services per your organizational needs
- Complete the rest of the wizard to ensure changes are implemented across the deployment
Expansion: In the case of expanding the hybrid deployment, such as adding more hybrid servers to the environment, the HCW should also be rerun.
- Add a new Exchange server to your on-premises environment.
- After the setup is correctly configured with your hybrid deployment, rerun the HCW.
- Navigate through the wizard and at the Hybrid Domains screen, choose the desired features for your new server.
- Complete the wizard to finalize the hybrid setup for the new server.
While expanding, it’s important to note that if additional servers are working with Office 365 for services like Mailbox Replication Services (MRS) proxy, Outlook Anywhere, or AutoDiscover, these new servers need to be added to the Send connector in Office 365.
Drawbacks and Solutions
One drawback is that there’s no built-in command or option to view the list of servers integrated into your hybrid configuration via the HCW. A workaround is using the ‘Get-HybridConfiguration’ PowerShell cmdlet which allows you to check the settings of the Hybrid Configuration object.

By utilizing the Hybrid Configuration Wizard effectively, MS-203 Microsoft 365 Messaging exam candidates can ensure successful maintenance and expansion of their hybrid environments within an organization, thus bolstering their skillset in managing Microsoft 365 Messaging effectively.
