Many people have multiple e-mail accounts—one for business use, another for personal use, a third for non-profit organizations you work with, etc. Occasionally, you might have to delete one of these. For example, if you change jobs, you'll want to delete your business account altogether. The following will delete the account on your iOS device. The account will still exist elsewhere, but to receive e-mail from it on your device, you will have to add the account back.
- Open Settings> Mail, Contacts, Calendars.
- Under Accounts, tap on the account you want to get rid of.
- Tap on Delete Account, and Tap Delete again when the confirmation screen pops up.
