However, when you finally give in out of frustration, your local account information isn't removed. You can still use it to log in anytime you're working off the Net and you'll have full access to your account. Accessing the computer over the network, however, requires your MS email and MS password. I couldn't find a way to use the local account credentials at least coming from a Win10 box.
