Yes, Aid4Mail 4 supports migrating to the Windows 10 Mail App.
However, Windows 10 Mail is an IMAP-only application. So rather than migrating your mail to a local file that would be imported into Windows Mail (as you might do with Outlook or Thunderbird) Aid4Mail needs to migrate directly to the mail server through IMAP.
To do this, you need to select "IMAP" on Aid4Mail's Target Format screen.
Then on the IMAP Settings screen, select your mail service from the drop-down list. If you're using a mail service that's not in the list, you can enter the IMAP settings manually. These will be the same settings you use in Windows Mail when you're setting up your account.
