Removing Exchange using ADSIEDIT is not supported.
The supported method would be to bring up a new server with the same name using the recoverserver switch, then run the Add/Remove steps and remove Exchange gracefully
This browser is no longer supported.
Upgrade to Microsoft Edge to take advantage of the latest features, security updates, and technical support.
Sorry if this has been asked before.
I was tasked with decommissioning our exchange 2016 server (or trying to). I have removed the mailboxes, and the mail database. I went to remove Exchange via control panel and it failed on the prerequisite check, stating unsupported operating system, which is odd, OS is Server 2012 R2 with all updates. The attached image shows the errors, is there a way to resolve this and properly remove Exchange?

Is the "Remote Desktop Host Manager." role installed on that server? If so, remove it first, then see if you can remove Exchange.
Hi,
Try uninstalling in CMD:
Setup.exe /IAcceptExchangeServerLicenseTerms /mode:Uninstall
I suspect everytime you run setup.exe it would check those prerequisites/requirements even though you are going to uninstall it, I would suggest to use ADSI.edit to remove Exchange directly: How to remove Exchange from Active Directory
