asked on Exchange 2013 Uninstall Error
Long story short...with the help of a consultant we moved from an on-prem exchange 2013 server to O365 a few years back. I thought that the on-prem server converted to a hybrid environment. As it turned out, I found out that it was not.
I have since setup an Exchange 2016 server in a hybrid environment and shut off the Exchange 2013 server. The Exchange 2013 server has been powered down for quite some time will not negative effects. I am now ready to remove the Exchange 2013 server from my environment.
I removed the mailboxes and whatnot on the Exchange 2013 server using powershell. I then went into the control panel to start uninstall Exchange 2013. It started to uninstall and then failed on Step 1 with the following error:
Error:
The following error was generated when "$error.Clear();

I canceled the installation and tried to run it again. Now it tells me:
An incomplete installation was detected. Run setup to complete Exchange installation.
Please help!!!

Then resume uninstall of exchange. If you again get an error on another language then you re-run the Microsoft ad remove utitlity and select uninstall an application and uninstall the new language.
There is no watermark entry in the registry. The only entries within the v15 folder are: Default, ConfiguredVersion, PostSetupVersion, UnpackedVersion.
I did download and run the microsoft ad remove utility. There is nothing called "TeleLanguagePacks for unified messaging" in the list. I have numerous entries for "Microsoft Exchange Client Language Pack", such as for Chinese, English, French, etc. I also have numerous entries for "Microsoft Exchange Server Language Pack" for various languages as well. Are those the language packs that you are recommend installing using the tool?
Thanks,
Chris
