Wow ... it's been a month since I asked this!
From the responses, I guess there is a third little piece of this, in RMM and also how much I want control over my user machines.
In many ways, I was almost considering them all just having fresh installs, like they went out and bought a new laptop from Best Buy, and now want to attach to Office365.
The files will be there, they can collaborate. Do I really need to provide anything else?
We are currently using an RMM solution still so I can run scripts and assist remotely if needed.
