Hi,
You can provide more information about this problem for our troubleshooting.
Is this installation a new installation or just an update from the previous version? Are there any other Exchange servers in your environment? What are the versions of them?
Which step did you fail in this installation and which role did you want to install? If you got the error message, you can post here and don’t forget to cover your personal information.
Note that you need check the system requirements and prerequisites, extend schema and prepare AD before installing Exchange roles. For more details about installation, you can use the
Exchange Deployment Assistant tool as a reference.
Regards,
Vera Shen
