Using New Outlook on Windows for professional communication and productivity
As far as I know, the only way to add accounts to Outlook (New) is within the program itself, not via the Control Panel.
At least, that's true with Windows 10. I haven't used Windows 11 yet, so I can't speak to that.
Cheers,

In Windows 10, I have verified that the only small icon in the Control Panel is "Mail (Microsoft Outlook)" and that definitely only connects to Outlook (classic), not Outlook (new). Outlook (new) ignores the Control Panel settings and also does not appear to allow the use of a login that is not the same as the email address.
I'll do a follow-up post with Windows 11 soon.
