Join Teams work meetings from Microsoft Teams (free) and vice versa

Microsoft Teams (Free) users can currently join Teams for work (or school) meetings only as guests, which requires them to use a browser and results in a sub-optimal experience. The new feature rolling out will allow these users to join Teams for work (or school) meetings in one click, without being redirected to the browser or asked to fill in their name/surname. They will also be able to continue collaborating with the meeting organizer and other participants via meeting chat after the meeting.  The feature will work in the opposite way as well, so Teams for work (or school) will just as easily be able to join meetings hosted by a Teams Free user with one click.

We ordered a server to be installed as a vmware server for lab purposes this fall. As we did this, and told the vendor what we wanted to do with the server, we were confident we'ld get a functioning server. 
Well, imagine our surprise when it turned out we could not install the VMWare softare. We ran into the problem and solution described in this post: It is up and running, but I'm sad to say it is true what the post say about disk preformance. So I guess I'm all ready looking for a new server.....
