Temporary Error 19 & Error 999

Occasionally, issues in Yahoo Mail can cause "Temporary Error 19" or "Error 999" to appear. These errors are usually temporary and will correct themselves within 30 minutes. If the error continues, here are some common causes and suggestions for fixing "Error 999" or "Temporary Error 19."

If the message also says that your account is temporarily locked, sign out of all browsers and devices and wait for at least 30 minutes. Repeated attempts to access your account while it's locked will prolong the lock period.

Why am I getting the error?

  • Sharing an Internet connection with others.
  • Your browser is not enabled to accept cookies from Yahoo.
  • Sending or receiving unexpectedly high amount of email at once.
  • Using a third-party software program or application to access Yahoo.
  • Spyware or viruses that can change system settings, preventing you from accessing some websites.
  • Unusually high activity from either your computer, mobile device, or IP address to specific Yahoo pages.
