Hello Vance M
Hi, I'm Karl and will be happy to help you today.
Just to clarify something. The "new Outlook" is not a replacement for the classic Outlook desktop program. It is the intended replacement of the Windows 10 / 11 Mail, People, Calendar apps. It is essentially "Outlook on the web" in an app framework with the added functionality of being able to add external IMAP accounts.
All classic Outlook desktop versions support POP accounts and PST files.
The following is a roadmap for "new Outlook"

To launch the desktop Outlook app, click on the Outlook icon in the Windows Start menu (assuming Office has been installed)
