Hi
Tried to run the script from
https://server-essentials.com/support/install-exchange-server-2016-in-existing-windows-server-essentials-2016-network
2016 Server updated, including 2016-06 from 27/06/19
And was informed it failed as needed to be digitally signed …
Ran Set-ExecutionPolicy -Scope Process -ExecutionPolicy Bypass
And Success
This is what works for me.
Set-ExecutionPolicy RemoteSigned
or
Set-ExecutionPolicy -Scope Process -ExecutionPolicy Bypass
