How to Fix Error 999
Error 999 is a relatively common error code that seems to occur with Yahoo sites and more specifically Yahoo Mail. Error 999 is Yahoo’s generic error code for many common problems occurring with their many services. The notice that pops up informs the user that this error is usually temporary and to try again later. So, patience may be all that is required and to try back at another time. Sometimes just refreshing the page can clear up the issue. If the problem persists, then the error may be related to the user’s system or network.

Error 999 may appear if a computer is infected with malware or a similar type of program that is attempting to use Yahoo Mail or another Yahoo service, unbeknownst to the user, in ways that are not allowed by Yahoo. If that is the case, or a possibility, a scan of the system for malicious programs may detect and remove the offending program. If Yahoo feels that a user is inappropriately using its service, it may provide the error code and prevent the user’s system or network from accessing the service. Such activity that Yahoo frowns upon includes exceeding Yahoo’s bandwidth limit. The error notice actually states that the problem may be due to unusual network activity such as too many automated queries coming from one IP address. Sometimes the activity is malicious, but sometimes it is innocent user error or overuse that brings about Error 999.
It is also possible that there are simply registry problems occurring in the computer system that are causing it to act incorrectly. Registry errors can be causing the internet browser to malfunction. A full system scan with a registry cleaner may help to alleviate this issue.
If nothing seems to work, changing the computer or IP address may help to gain access to Yahoo’s services. Sometimes, a new IP address can be generated by restarting the modem.
