IMAP/Windows 8 Outlook 2010

New Windows 8.1 HP envy machine with a copy of Microsoft 365 installed, trying to get Zoho mail setup in Outlook following all IMAP instructions.  Does not get mail, keeps making me put in my password loop.  Any ideas or people have other similar problems?  I also couldn't get it set up in the Mail app either.
