Ok I just came back to the community after dealing with every possible issue and still am in the middle of a major issue, but also like you I absolutely love my preview builds.  I started out as a small company that grew rapidly with major data security compliance issues within the past two years so aside from having to deal with that issue I will address that in a different post can I ask a question because what your talking about is an issue that I dealt with extensively.  I have a work account and a personal account on my pc I don't access my personal account on my office 365 portal, I do on my outlook 2016 but both accounts are separate even with authentication methods,  I have a tablet that is setup with two different systems one personal one business on the tablet I have no single sign on ability.
