any idea , i find also these services in server :

  • The error message generally comes when there is a conflict with registry in the server (The screenshots already testifies that Exchange Server uninstallation was not successful).

    If you server is a VM:  best way is to restore previous snapshot before installation.

    Additionally, check for Server name in schema from ADSI, as with same server, there will be conflict. Try to rename the server and install the same.

    If the server is a physical server: Worst case scenario: Server staging, with formatted OS.
