Can I change iPhone mail auto fill?

Hey 2Petunia,

Thanks for clarifying. If you mean you want to change the email account being used as a default to compose mail messages, we have steps for that.

You can change the account, but it will need to be an account you have configured for use with Mail on your iPhone.

Go to Settings > Mail. Scroll to the section for Composing, then tap on Default Account. Tap the account you wish to have autofilled for the From address to compose email messages from.

If you are not referring to autofilling when you compose a message, reply back with where you want the account address to autofill.

Take care.
