Hi all,
I have a problem with the installation of the Cumulative Update 20 for MS Exchange 2016 on a fresh VM (So currently, there is no Exchange installed). I first installed .NET and the other required prerequisites and then I started the setup with an appropriate admin account (which is a domain admin, an organisation admin and a schema admin) using the command line with the attribute /prepareAD. This worked fine.
Afterwards, I tried to start the actual installation with EXCHANGESERVER.msi. Then, a window opened, which disappeared after about 3-5 minutes without an error message. However, nothing was installed.
I have to say that Exchange 2016 was already installed on another VM (which does not exist anymore but had the same computer name) in the same domain. I have also deleted all Exchange entries from the AD.
I hope you can help me. Thank you!
