Im using the stock email app that came with my Note 2. frequently, I keep getting email notifications stating ' Your account*_____*could not be authenticated. If you have recently changed your email password, please enter the most current password in settings to continue receiving emails'. ive received this email for my added yahoo, gmail and other emails accounts. I havent changed the passwords on any of these email accounts and know the passwords are correct. sometimes I have to edit the email accounts and reenter the passwords in the app, multiple times in order to get the account working again.
I like using one email app that has all my accounts, rather than a yahoo app, gmail app, etc.
