-ERR Element not found.
While debuging an POP3 account, I found that the POP3 server (Exchange 2003) was returning "-ERR Element not found." when accessing the account and enterring the password.
I thing that this was related to the Cannot found LSA Authority when accessing the same account using the Exchange Outlook webaccess.
This is because the password is not valid. I'll debug it when I will have the time, for now, I just resetted the password and everything worked fine.
