The url is talking about how you can extend AD scheme for Exchange. You can perform the scheme extension without installing the Exchange server.

Hi @Kuronuma,
You can prepare Active Directory and domains on a server like domain controller to extend the AD schema without actually installing Exchange, but you need to first install the prerequisites.
If you are still having trouble with this process, please share screenshots of the error message when you run the preparation cmdlets.
Hi @Kuronuma, I am writing here to confirm with you how thing going now? Please let us know if you would like further assistance.

Hi,
Can I install it offline so that if I dont have internet connectivity I can able to perform Exchange schema extention an all
Yes. You should be able to install Exchange without internet if you have downloaded and installed the prerequisites and the Exchange iso file. (you can download these files on a device which has access to internet then copy these files to Exchange server)
