Using New Outlook on Windows for personal email, calendar, and contact management
Do I understand correctly - You are trying to add a POP email account to New Outlook for Windows but are not allowed to specify the account details and server settings. Because Outlook has already done an "Auto Account Add" based on you entering only the email address?
If so, then you will have to force Outlook to let you use Advanced/Manual setup. See the Answer by "Hornblower409 Jun 5, 2026", "New Outlook for Windows - Force Advanced/Manual Setup" at

If this is not the case, please provide some more details or try to describe the problem to me in a different way to help me understand.
