Update... when I logged out and logged back in, then restarted Evolution, the left-side pane filled with my multiple attempts at creating EWS and MAPI accounts. So the account gets created, but doesn't appear in the list for some reason.
I had to kill all Evolution processes to regain control of my desktop. I deleted all Evolution-related configuration and database files in my home directory and rebooted. Then I first configured a Gmail account, which the wizard took care of automatically. Then I configured an IMAP account (connected to my home Ubuntu server built with mail-stack-delivery and amavisd-new-postfix). This also worked. Finally, I configured an EWS account and, this time, it showed up in the list and is working fine.
So it appears that the initial install of Evolution (and possibly evolution-ews) leaves the system in some kind of incorrect state.
