Outlook 365 ('classic') won't connect to Zoho email

Outlook 365 ('classic') won't connect to Zoho email

New computer, fresh install of Office desktop. On the old computer Outlook was working fine with Zoho, retrieving/sending mail, etc.  On the new one I can't connect the accounts in Outlook--Outlook just keeps popping up the box asking for a password. All the settings match those recommended by you, TFA is off, and the password works to log in to Zoho proper. How can I get Outlook to connect?
