2019 mail application showing password prompt

A blast from the past!

The "2019 mail application" you're referring to is likely the classic Windows Mail app that was included with Windows 7 and Windows 8. This app has been replaced by the newer Mail app in Windows 10, but I'll do my best to help you with your issue.

If you're seeing a password prompt when trying to access the 2019 mail application, it's likely because the app is trying to connect to your email account using an outdated authentication method. Here are a few possible solutions:

  1. Check your email account settings: Make sure your email account settings are correct and up-to-date. You can do this by going to the "Accounts" section in the Mail app and checking the settings for your email account.
  2. Update your email account password: If you've recently changed your email account password, try updating the password in the Mail app. You can do this by going to the "Accounts" section and clicking on the "Change" button next to your email account.
  3. Try using a different authentication method: The 2019 Mail app may be using an outdated authentication method, such as POP3 or IMAP. Try switching to a more modern authentication method, such as OAuth 2.0 or Microsoft Authenticator.
  4. Uninstall and reinstall the Mail app: If none of the above solutions work, you can try uninstalling and reinstalling the Mail app. This will reset the app to its default settings and may resolve the issue.

Here are the steps to uninstall and reinstall the Mail app:
