Error 401 0: Unauthorized and login failed for Yahoo and Hotmail emails

[aomorgan]

I've had my phone for a little over a year and have never had an issue with the email app. A few days ago every time I would try to check my email it would give me a log in failed error. I've tried to re-enter the passwords, which I know are correct because I can check my email on the computer, and it gives me the error 401 0: Unauthorized. It gives me the same error when I try to delete the accounts to set them back up as well. Any suggestions on what to do would be appreciated.
