I think you uninstalled Microsoft Exchange Server incorrectly and now you are unable to remove it completely. Here is an example how to properly uninstall Microsoft Exchange Server 2010. Before you start uninstalling the application, you need to make sure that each server roles meets the right prerequisites and system requirements. To know more about the server roles, visit Overview of Exchange 2010 Server Roles.

To know the prerequisites for all server roles, visit Microsoft Exchange 2010 Prerequisites. Now to begin uninstalling Microsoft Exchange Server 2010, click Start, Control Panel, and then select Microsoft Exchange Server 2010. In the Maintenance Mode page, click Next. In Server Role Selection screen, select all server roles to remove the entire installation and then click Next.

In Readiness Checks screen, check the status to verify if the server role prerequisite checks finished successfully. If the check doesn’t complete successfully, examine the Summary page to troubleshoot and fix the problems that are stopping Setup from finishing. Once the checks have successfully completed, click Uninstall. In Completion screen, click Finish. And you’re done.
