Hi @mtb,
Currently, the Microsoft Q&A community only supports English, please convert your question to English.
Based on the translation, my understanding of your question is that an error was encountered during the installation and upgrade of Exchange.
For this error, I found three methods for you. If you are recovering from a lost Exchange server and only need the "Setup /mode: RecoverServer Recover this Exchange Server" method mentioned in the message, please refer to the following.
If you want to reinstall a new one, please make sure that the previously installed Exchange on this server has been uninstalled, and then try to rename the server or use ADSI to clean up the AD and try again. More details, you can refer to:
