The advanced configuration will allow me to specify an SMTP user name but there is no way to configure the IMAP user name being different from the email-address.

    Yes - I think this is exactly what's happening. Some IMAP providers can apparently parse this - the ISP I'm using does not.

    I'm working with them to see if they can discard the "@domain.com" part of my forced Outlook (new) IMAP login - but it's not looking promising.

    It may also be that Outlook new is sending the "user @ domain.com" first, then "user" as it logs in - but some IMAP providers disconnect after the first failed attempt. I can't get enough of a trace with my ISP to tell if that's the case.

    Ergh - now Outlook 365 is trying to get me to switch to Outlook New - which immediately failed after it imported my IMAP settings.

    UPDATE: After I told Outlook (new) to go back to Outlook 365, it hasn't asked me to migrate again. So - my Office 365 workaround is still in place for now.

    2nd UPDATE: However - new Outlook is force loading. If I uninstall Outlook (new) - reboot - verify that everything is clean - then start Office 365 - Outlook (new) is automatically loaded.
