To resolve this issue:

  1. Download the Service Pack 1 (if you have removed it).
  2. Run the installer and accept the EULA.
  3. Select "Uninstall" .
 
If you already installed patches post SP1, then you should go through the uninstallation for each of them in reverse order (as described in this article) for Service Pack 1.

Once the uninstallation is complete, check if the Transport Agents are now visible, “Get-TransportAgent”. If so, continue to install Service Pack 1. Make sure to disable the following services before reinstalling Service Pack 1:

  • MsExchange Transport Service
  • World Wide Web Publishing (W3P) Service
  • MsExchange Diagnostic Service
 
Back up the SMEX server before running the uninstallation process.
