Extending Active Directory schema without purchasing exchange 2019

[Kevin_Poulton]

Setting up for hybrid office 365 environment, from green field site.

We are looking to extend the AD Schema etc, on a Windows 2019 Server (running on a virtual server), but not looking to run on Prem exchange server.

Is there anywhere to either get an evaluation copy of Exchange 2019 or just the set-up routines? or a very detailed step by step guide of what we would need to do manually.

Thanks

The 2019 binaries are hard to get to, but you don't really need them - any version would do.

Thanks, do you know  where I can get 2016 binaries then. @Vasil Michev
