Uninstall Azure AD Connect

We like to uninstall Azure AD Connect. The organization will not use Azure AD Connect anymore to sync AD objects between on-premises AD and Azure AD because the servers are moved to the cloud. This is when we like to delete Azure AD Connect. In this article, we will look at how to remove Azure AD Connect from server.

Locate Azure AD Connect server

Start PowerShell as administrator. Make sure that you have privileges to search in Active Directory. After running the cmdlet, we do know that it’s installed on the server DC01.

PS C:\> Get-ADUser -LDAPFilter "(description=*configured to synchronize to tenant*)" -Properties description | % { $_.description.SubString(142, $_.description.IndexOf(" ", 142) -142)}
DC01

Turn off directory synchronization

Disable directory synchronization in two places:

  1. On-premises AD
  2. Azure AD

Turn off directory synchronization on-premises AD

Sign in to the Windows Server, where you have Azure AD Connect installed and configured. Start PowerShell as administrator and run Import-Module ADSync. Follow with the Set-ADSyncScheduler cmdlet to stop the synchronization.

PS C:\> Import-Module ADSync

PS C:\> Set-ADSyncScheduler -SyncCycleEnabled $false

Turn off directory synchronization Azure AD

In the same Windows PowerShell window, install and connect to Azure AD.

PS C:\> Connect-MsolService

Turn off directory synchronization and convert your synchronized users to cloud-only. Run the Set-MsolDirSyncEnabled cmdlet to stop the synchronization.

PS C:\> Set-MsolDirSyncEnabled -EnableDirSync $false

  1. Just want to double-check, so before removing Azure ADC we would need to ensure that new user objects were created in Azure as the sync’d objects would not really be useful going forward.

    Would this be a fair statement?

    Thanks in advance

  2. Hi Ali, Thanks for the article.

    So after removing the Azure AD Connect – we can change password, make changes to user accounts, groups in M365 directly right?

    As with Azure AD in place we cannot make changes to M365, all changes gets synced from Local AD.

    Thanks,

    1. Hi Jatin,

      That’s correct. As long as your AD (Authority) is on-premises, you should keep Azure AD Connect and manage everything on-premises.

      Suppose there is no need anymore to manage users from on-premises and no longer require directory synchronization or password synchronization. In that case, you can uninstall Azure AD Connect and manage everything in Microsoft 365.
