Windows defender access denied

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. Upon initially running Exchange Setup via the GUI on the administrative workstation and selecting only the management tools option, I received a message indicating that a previous installation had been attempted, and would I like to try to continue with that installation, to which I responded Yes.

I had tried to install the management tools previously, but the installation at that time failed. However, I do not recall what the specific installation error was for that failed installation attempt. After allowing the Exchange installation to continue, the result was that the installation completed successfully, but appears to have installed a full instance of Exchange Server on the workstation, not just the management tools. This has now resulted in the administrative workstation now hosting shadow queues for Exchange, which is intefering with mail delivery the intended environment is just a single-server Exchange installation.

They recommended creating a brand-new Exchange user mailbox, with the user being a member of Domain Admins, Enterprise Admins, Schema Admins, Organization Management, and the affected workstation's local Administrators group, then logging into the workstation under that account and attempting to uninstall Exchange from an elevated Exchange Management Shell session.

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.
