How to manually remove an Exchange 2007 that got hosed.

Uninstalling exchange was also unsuccessful because some objects were missing from Active Directory. I also wanted to avoid reinstalling the OS as I have critical software that needs to remain.  So I tried removing exchange manually.

  1. Run setup /m:uninstall (From Exchange 2007 Media)
  2. Stop and disable all the Exchange 2007 services
  3. Use Registry Editor (Start->Run->Regedit) to remove these Exchange related registry keys:
    • HKLMSOFTWAREMicrosoftExchange
    • HKLMSYSTEMCurrentControlSetServicesMSExchange* (all the keys starting with “MSExchange”)
    • HKLMSOFTWAREMicrosoftWindowsCurrentVersionUninstallMicrosoft Exchange
  4. Remove the entire Web Server role (don’t forget to reinstall afterwards as it’s a prerequisite for E2K7!)
  5. Remove the Exchange 2007 server from Active Directory. I ended up deleting the entire “Microsoft Exchange” branch from ADSIEdit (Configuration Container > Services > Microsoft Exchange) as my domain only has one server.
  6. Use Windows Explorer to delete:
    • C:Program FilesMicrosoftExchange Server
    • C:ExchangeSetupLogs
  7. Use Windows Installer CleanUp Utility to remove all the exchange related info from the installer database.
  8. Remove the security groups created by Exchange setup from AD

Note: Manually removing Exchange 2007 is not supported by Microsoft! Official guidance for removing Exchange 2007 can be found in this TechNet article.
