Tutorial / Cram Notes
Unregistering a tenant directory in Microsoft Azure Stack Hub is an important task for system administrators when they need to remove an Azure Active Directory (AAD) or Active Directory Federation Services (AD FS) from their Azure Stack Hub deployment. This action is typically required when you no longer need a directory to be associated with your Azure Stack Hub or when you’re decommissioning a service.
Before proceeding with the unregistering process, it is essential to understand that this action cannot be undone and should be performed carefully. Additionally, ensure that no users or services are reliant on the directory you are planning to unregister.
Steps to Unregister a Tenant Directory in Azure Stack Hub:
- Sign in to the Azure Stack Hub administrator portal: Access the Azure Stack Hub administrator portal using an account with owner permissions on the ‘Default Provider Subscription’ where the directory is registered.
- Navigate to the directory management section: Go to the ‘Region management’ blade and then select ‘Identity systems’. Here you would see the list of registered directories.
- Select the directory to be unregistered: From the list of directories, identify and click on the tenant directory that you want to unregister.
- Initiate the unregistering process: After selecting the directory, find the ‘Unregister’ action – usually located at the top of the management pane or under more actions denoted by an ellipsis (…).
- Confirm the unregistering: You will likely be asked to confirm your action. Be certain that you are ready to remove the directory, and be aware of the consequences. Confirm your choice to proceed with the unregistration.
- Monitor the unregister process: The process might take some time depending on the system and the number of resources that were connected with the tenant directory. Monitor the portal notifications or the ‘Region management’ blade to confirm when the process is completed.
Post-Unregistration Considerations:
- Service Disruption: Any services or resources that were using the directory for authentication will be unable to authenticate users. Make sure to inform users about this and plan accordingly.
- Update Application Configurations: If you had any applications using this directory for authentication, remember to update their configurations with a new identity provider if necessary.
- Data Cleanup: Depending on your organization’s data retention policies, you might need to backup or delete any remaining data associated with the tenant directory.
- Inform Stakeholders: Make sure all relevant parties are informed about the removal of the directory to prevent confusion and to coordinate any necessary actions on their part.
By following these steps, system administrators can successfully unregister a tenant directory from their Azure Stack Hub deployment, thereby ensuring that the system stays updated and clean from unnecessary configurations. Remember that the specifics may vary slightly based on the version of Azure Stack Hub and the current system configuration, so always refer to the most current Azure Stack Hub documentation for any updates to procedures.
Practice Test with Explanation
True or False: Before you begin the process of unregistering a tenant directory, you should make sure that there are no active subscriptions or resources in that directory on your Azure Stack Hub.
- True
Unregistering a tenant directory should only be done if there are no active subscriptions or resources, as these need to be cleaned up before the directory can be successfully unregistered.
Select Single: What PowerShell module is primarily used for unregistering a tenant directory in Azure Stack Hub?
- A) AzureRM
- B) AZ
- C) AzureStack
- D) AzureAD
C) AzureStack
The AzureStack PowerShell module contains cmdlets specifically for managing Azure Stack Hub resources and configurations, including the unregistering of a tenant directory.
True or False: You can unregister a tenant directory using the Azure Stack Hub user portal interface.
- False
Unregistering a tenant directory is not an action completed through the user portal. This action must be done using PowerShell commands.
Multiple Select: What should be considered before unregistering a tenant directory? (Select all that apply)
- A) Back up all the data associated with the directory.
- B) Ensure no other Azure Stack Hub services depend on the directory.
- C) Make sure that all user subscriptions are in a “Disabled” state.
- D) Confirm that the tenant directory is connected to the internet.
A, B
Before unregistering a tenant directory, you should back up all data associated with the directory and ensure no other services depend on it. Subscriptions should be deleted, not just disabled. Internet connectivity is not relevant to the directory itself but may be necessary for the Azure Stack Hub to communicate with Azure.
True or False: To unregister a tenant directory, you need to be signed in to the Azure Stack Hub administrator portal with owner privileges.
- True
Administrative or owner privileges are required to perform directory unregistration actions in the Azure Stack Hub administrator portal.
Multiple Select: What are the correct steps in the process of unregistering a tenant directory? (Select all that apply)
- A) Remove all the directory’s guest users from Azure Stack Hub.
- B) Use the Unregister-AzureStackHubDirectory PowerShell cmdlet.
- C) Delete the home directory or primary domain of the Azure Stack Hub.
- D) Ensure there are no guest directory tenants remaining.
A, B, D
Key steps to unregister a tenant directory include removing all guest users, using the appropriate PowerShell cmdlet, and ensuring no guest directory tenants remain. Deleting the home directory is not a step in this process.
True or False: The Azure Stack Hub administrator needs to remove the directory tenant from the Azure AD to unregister a tenant directory.
- False
Removing the directory tenant from Azure AD is not part of the unregistering process in Azure Stack Hub. Unregistering is done through Azure Stack Hub PowerShell modules, and Azure AD management is separate.
Select Single: What is the consequence of not unregistering unused tenant directories in Azure Stack Hub?
- A) Improved performance of Azure Stack Hub
- B) Possible directory conflicts or security concerns
- C) Automatic deletion by Azure Stack Hub
- D) No consequences; unused directories do not affect the system
B) Possible directory conflicts or security concerns
Unused tenant directories can lead to directory conflicts or security concerns because they may still contain outdated or unnecessary permissions and configurations.
True or False: Customer billing details are automatically deleted after unregistering a tenant directory from Azure Stack Hub.
- False
Billing details are not a part of the tenant directory registration and need to be managed separately. Unregistering a tenant directory does not delete billing details for customers.
Select Single: Which one of the following is a prerequisite for unregistering a tenant directory in Azure Stack Hub?
- A) Establishing a VPN connection to Azure
- B) Configuring multi-factor authentication for all users
- C) Deleting all the resources and subscriptions in the tenant directory
- D) Installing the latest updates for Azure Stack Hub
C) Deleting all the resources and subscriptions in the tenant directory
Before unregistering a tenant directory, all resources and subscriptions associated with that tenant directory in Azure Stack Hub must be deleted to avoid orphaned resources.
True or False: You must contact Microsoft Support to complete the unregistering process for a tenant directory in Azure Stack Hub.
- False
While Microsoft Support can provide assistance, you do not need to contact them to complete the tenant directory unregistering process. This can be done using PowerShell commands by the Azure Stack Hub operator.
Select Single: After unregistering a tenant directory, can you re-register the same directory at a later time?
- A) Yes, but only after a mandatory waiting period.
- B) Yes, as long as it is not already associated with another Azure Stack Hub instance.
- C) No, once a directory is unregistered it cannot be reused.
- D) No, directories are unique and can only be registered once.
B) Yes, as long as it is not already associated with another Azure Stack Hub instance.
A tenant directory that has been unregistered can be re-registered with the same or different Azure Stack Hub instance provided that it’s not currently associated with another instance and that any previous resources and subscriptions have been properly cleaned up.

This blog post is really helpful. Thanks!
I don’t get why unregistering is so complicated. Microsoft should make this more straightforward.
I agree it’s a bit tedious. Proper guidance and documentation can mitigate these challenges though.
Most cloud platforms have complex underlying infrastructures; better safe than sorry, I guess.
