How licensing works for work and school accounts in the new Outlook for Windows

AllenFilush  Thank you so much for the detailed response.  You answered all my questions, and I understand the plan.  Thank you!

Just to follow up to your question about my term "deployment," no implication in any direction was intended, it was just the only word I could find in my brain after a long day.  Your point about pricing is understood; I think what I was trying to understand was something like "If New Outlook's primary account is a paid Microsoft 365 personal or family account, is that different than New Outlook's primary account being an E3 or E5 account?  Are the two license types identical in terms of New Outlook functionality they enable?  If not, what differences are there?"  From your response, I infer that they are identical - that New Outlook can be placed in premium mode with either a paid Personal/Family 365 account, OR with a paid BusStd/Prem/E3/E5 account, and it will then behave identically regardless of which license type is used to enable it.

Yes, I did notice the large number of feedback items for Outlook, and now that the vision is more clear, I'll look forward to seeing what you do with in the future.  Thanks again for your presences and response here.
