Microsoft Exchange Server is software, and from your post I understand that you want to replace it hardware. That's impossible. You can't replace software by hardware, not that software anyway.
End of the story.
Better find someone to do set it all up. His first step will be to get the requirements clear.
Hello all. Two years ago I was assigned the task of taking our office from an outdated and small local server to a Microsoft Exchange server and it's been a disaster on the part of Microsoft so I'm looking into switching back to a local server. I have zero idea how to use them, let alone set up and maintain or research to find the right one. We're on Windows 10 and have 5 PCs I need to network. I'm looking for input from you on: which one to choose, good YouTube tutorials, etc. Thank you in advance.
