Using older versions of Outlook for Mac in business environments
It was explained to me the other day that Microsoft will no longer accept POP/SMTP interactions, however other servers (who I talke to) will continue to work in Outlook 2016. So, this means that if you are using Microsoft emails like hotmail, live etc. you must begin using the Exchange method to syn with Outlook, but other emails that are not Microsoft will continue on as their servers (unless notified otherwise) will not be affected. If you are on a browser checking your email, this won't affect you either.
