How do I change my iPhone or iPad's SMTP (outgoing) password?

To change your SMTP (outgoing) email password on your iPhone, follow these settings:

1. To get to this setting, click on the SETTINGS icon on your iPhone.
   Once on the settings screen, scroll down to MAIL > CONTACTS > CALENDARS, and select it:
   
2. Then click on the account you need to update the SMTP password for:
   
3. Next, click on the OUTGOING SERVER.
   
4. Now you will see a list of OUTGOING SERVERS that have been configured on your iPhone or iPad. Select your email domain:
   
5. Now you will see the settings for that PRIMARY OUTGOING SERVER:
   Make sure that:
   • SSL is OFF.
   • Authentication is set to "PASSWORD".
   • Outgoing Port is set to "587".
   
6. And don't forget to enter your new password!
   Click "Done".
   It will VERIFY these settings. If it does NOT verify, something is wrong. It could be that your password is typed incorrectly or did not get saved to this part of the email setup.
   Type in the password for your email account again if you're getting an error, and see if that helps.

It should verify. Then simply click back to the main settings window.

Done!
