How do you sign out of yahoo email? because I only used it once and don't ever want to use it or any emailing again on my phone. I can't seem to do it it's probably something simple lol
If your Yahoo! account is configured via the iOS mail app, then all you have to do is go to Settings-Mail, Contacts, Calendar, select your Yahoo! account and select "Delete Account" at the bottom of the screen. There is no 'logout' feature with the default mail app.
