i was using my email just fine up until this morning.
i finished what i had to do and went on my work and later i tried to use it again but it was logged off ( did not logged out my self) and it said that it doesnt recognize my emai.
I cleared my cache/cookies, i even tried to put my phone number but it didnt recognize it.
i also tried to send an email to the non-recognizable account from a different yahoomail i am using and it got back a failure to deliver notice with the following code: This mailbox is disabled (554.30). - mta4013.mail.ne1.yahoo.com
