Yahoo Mail Error 15 is a common issue that occurs when there's a problem with the browser or temporary access restrictions. It usually relates to the inability of Yahoo Mail to load properly due to browser or server-related issues. Here are steps to resolve it:

Steps to Fix Yahoo Mail Error 15:

1. Clear Browser Cache and Cookies:

   • Old cache and cookies may cause compatibility issues. Clear them from your browser's settings, and restart the browser.

2. Update Your Browser:

   • Ensure you are using the latest version of your browser. An outdated browser can lead to performance issues with Yahoo Mail.

3. Try a Different Browser:

   • Switch to a different browser (Chrome, Firefox, Safari, etc.) to see if Yahoo Mail works properly.

4. Disable Browser Extensions:

   • Ad blockers, privacy extensions, or other browser add-ons might interfere with Yahoo Mail. Disable these extensions and check if the error persists.

5. Check Internet Connection:

   • Ensure your internet connection is stable and fast enough to load Yahoo Mail. Resetting your router can also help.

6. Disable VPN or Proxy Settings:

   • If you're using a VPN or proxy server, try disabling it temporarily. These can sometimes interfere with Yahoo Mail’s ability to connect.

7. Use Basic Yahoo Mail:

   • If the full version of Yahoo Mail isn’t working, switch to the basic version by clicking “Try Basic Mail” at the bottom of the Yahoo Mail login page.

8. Check Yahoo’s Server Status:

   • If Yahoo’s servers are down or undergoing maintenance, you may experience Error 15. You can check Yahoo’s server status or wait and try again later.

By following these steps, you should be able to resolve Yahoo Mail Error 15 and regain access to your account.
