Outlook account and exchange

I know that outlook.com email accounts can be set up as exchange. I have done that before. I just had to delete my account and it will no longer allow me to set it up as Exchange, and if I set it up as Outlook the calendar no longer works. When I try to set it up as Exchange, I get a screen from Microsoft asking if I am trying to sign into emclient. When I say “continue,” nothing happens. I cannot finish the setup. It simply stalls.
