Exchange 2016 Uninstall Fails on Mailbox Server Role: Client Access Service
Recently I battled with this headache of an Uninstall of an Exchange 2016 server. In the Exchange Install Logs this is the error that you are seeing.
ERROR ( message:Cannot find GLOBAL MODULE object with identifier “exppw:)
To resolve this error, you can follow the below steps.
- Copy the following file from a working Exchange Server: “C:\windows\Systems32\Inetsrv\config\applicationhost.config”
- Replace the applicationhost.config file on the Exchange server that does not want to uninstall.
- Restart the uninstall process again.
