Since I updated four devices with operating system 17.3. My exchange
account keeps telling me “Password Incorrect Enter the password for the
exchange account “Exchange”. I have
changed the password once and deleted the Exchange account and created it again
several times. I keep getting the same message and exchange does not work.
Since I can get email through other devices which do not use Exchange, my
password is correct. I have tried advice from Sup_Traste and deleted my
Exchange account and created a Outlook.com account and got what I wanted, Mail,
Calendar, Contacts, Reminders, and Notes. Now I can synchronize my Outlook on
my PC to my iPhone and iPad. I also use Authenticator and it was a seamless transition.
