How can I uninstall exchange properly? Because now some error appears during uninstallation

saifs1980 · Answer

delpiotr&nbsp;&nbsp;Since you have deleted the exchange server on which upgrade had to be done. Now uninstallation will also not succeed properly since the actual server container in ADSIEDIT has been removed. Whether its installation or uninstallation the setup looks at the server container in ADSIEDIT and this server container is also replicated on all DCs.&nbsp;So now you will have to do a manual exchange uninstallation. You can follow below article for manual exchange cleanup and then setup a new exchange install if you require.https://www.solvps.com/blog/?p=583&nbsp;&nbsp;
