Server rejecting signon due to "invalid user name or password"


Server rejecting signon due to "invalid user name or password"

Frequently I can not sign on to my ATT Yahoo mail account using Outlook. message says "invalid user name or password". Perhaps 1 hour later or the next day it will work fine. Lately it is failing more often than not. Does anyone have a solution for this problem. My computer is using a wireless connection through a nother desk top. Signal is excellent and the other computer works fine.  Thanks
