Hi there, SirFrank.

Aside from what you've already tried, you also need to generate an app password. This is required by AOL since you're accessing it via a third-party email app and the new password isn't recognized by QuickBooks yet.

Here's how:

1. Go to AOL's account security page.
2. If prompted, sign in to your account.
3. Select Generate app password.

   Note: If this option doesn't appear, you'll need to enable 2-step verification.

4. Select the app you use from the drop-down menu.
5. Select Generate.
6. Follow the instructions provided to use the app password, then select Done.Note: You can also stop the app password by managing it.

Let me also share these articles for more details:
