You can not run enterprise business functions on a pi unless your “enterprise” is made up of a single user.
Even something like basic video steaming for internal training videos would kill it due to encoding issues. Let alone the impact from one service affecting others like a user file transfer affecting the speed of messaging or email, or a complex database activity momentarily taking out your task management application.
You would need a dozen of them for splitting services and redundancy, then a UPS and redundant internet connections. It would end up costing you a few thousand dollars just in hardware before you even started paying someone to set it up and keep it running.
We selfhost a lot for work. Was paid services before but cost kept creeping up. Companies have IT anyway, so it is really not a huge expense to manage your own services.
Many of the things you listed are available as free software through opensource projects. Microsoft just bundles it all making it easy.
And runs the server required stuff on their own hardware.
I mentioned this in my comment.
Which is cheap. You can run a lot on a pi these days. Or setup a higher powered nuc. MS chargers for server and now named user licenses.
