I am unable to uninstall Exchange Server on a Windows 10 v computer. Running setup. Win32Exception: Access is denied. What do I need to do so that Exchange Setup passes this prerequisite check to allow Exchange to be uninstalled from the administative workstation?
As background, I was trying to install only the Exchange management tools on a workstation that is used for system administration.

This failed with the same error as previously described. Their next recommended action was to delete the workstation-based Exchange server from the Exchange configuration via ADSI Edit, under the following location:. I was aware of how to do this, but was reluctant to take that step out of concern of leaving "debris" in the Exchange configuration. But since other steps were not working, this is what I ended up doing. Hopefully there will not be any repercussions from such a "brute force" method of removing the errant workstation-based Exchange server from the organization.
I didn't pursue this, though, because I opted for the brute force removal method, making collecting this data moot. Products 70 Special Topics 19 Video Hub Most Active Hubs Microsoft Teams. Azure Active Directory.
