I'd like to begin setting up a local Sharepoint server (not online version) for a nice document repository. We can spin up Windows 2012 servers and plan to do 2016 next year (so SP 2019 is out for now, but I would like to know more about it). We're looking to have four of us access the repository at first and then expand later.
I dabbled in Sharepoint 2007 a dozen years ago with the whole MOSS deal and honestly it got way too complicated with out consultant and we never used it to its full potential. I hear 2019 has all sorts of streamlined content but for now we have to build 2016. As I mentioned we can't go online with our materials like the 365 route but a simple local server would do just fine.
So, after doing some research, I'm curious what the EE community has to say for what guides and online training they've used, free preferred.
