"incorrect authentication data"

All of the sudden it is saying the server is saying “incorrect authentication data” and says my password is incorrect. Please help!!!,

I seem to have the same problem, from which I am desperate.  Nothing seems to help, cannot find “forgotten password” or “change password” possibilities.  Can anyone help out?  Thanks.


Hello all,

If your account is set as IMAP, could you try deleting the account and configuring it again? Let me know if the auth window popped up again afterwards.
