Hi @Balmukund Shrivastava ,
As far as I know, Microsoft 365 Apps isn't supported on Windows Server 2008 R2, Windows Server 2012, Windows Server 2012 R2, or Windows 2022. Please check if your environment in the following document.

If your organization is using a version of Windows Server that doesn't support Microsoft 365 Apps, we recommend that you move to Windows 365 or Azure Virtual Desktop.
