A few days ago I acquired a desktop computer with Win 10 Pro and have been having nothing but extreme trouble getting Outlook 365 to work. On my old computer with Win 7 it worked just fine. Now I get stubborn complaints about everything I try to do; can't log in, can't change password. For some reason I don't recall I created an address "(e-mail address removed)" Now I can't get rid of that and of course no one knows who that is. My real address is "(e-mail address removed)" but now I keep being told that is part of a domain, or some such thing. I would just forget about Outlook and use a much less troublesome client except for all the saved mail I have on Outlook. If someone has a solution, please tell me.
