- Microsoft Entra Connect must be installed on a domain-joined server that runs Windows Server 2022, Windows Server 2019, or Windows Server 2016. We recommend Windows Server 2022. You can deploy Microsoft Entra Connect on Windows Server 2016. However, since Windows Server 2016 is in extended support, you might need [a paid support program](/lifecycle/policies/fixed#extended-support) if you require support for this configuration. Installing on unsupported versions of Windows Server may cause service failures or unexpected behavior.
