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.

    I have probably found a solution:

    Control Panel (small icons)

    Mail

    add account,

    go "manual" all the way

    It turns out I had Office 365 with the old Outlook on my computer - so I'm using that with Windows 10. They're discontinuing "Old Outlook" - but not before Windows 10 expires. I figured I'll deal with the whole thing in October 2025.

    Meanwhile - on my Linux box, even though I hate the UI, Thunderbird with the TB Sync extension is working decently. You have to add the Exchange ActiveSync (EAS) plugin to TB Sync for Windows Live calendars, but once you have it setup, you don't have to mess with it. Not my preferred solution - but there you go. This may be my ultimate solution after October 2025 - not sure yet.

    UPDATE: TB Sync users are reporting issues as of March 6th with Outlook Calendar integration. This may not be a solution anymore. Thunderbird can still get mail from Outlook servers - but lack of calendar integration would make it a no-go. Investigations ongoing.

    I have the same problem, because in a new office installation there's only the new outlook in the package. I have several email addresses on a web-server, the login doesn't work with the emailadress, the username field for IMAP and SMTP is necessary to make new outlook usable.
