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 you get a Temporary Error 19 or Error 999 message telling you your account is temporarily locked, sign out of all browsers and devices for at least 30 minutes, then try accessing your Yahoo again.
