How to Remove an Email Account From an iPhone
Email accounts accessed through the Mail app are managed not from Mail, but from iOS. So to add or remove an account, you’ll work through the Settings app, not the Mail app.
Considerations for Email Account Removal
Before you remove an email account, evaluate the implications.
Deleting an Email Account Removes all Emails From the iPhone
IMAP, POP, and Exchange, as well as accounts configured with automatic settings (such as Gmail, Outlook.com, and iCloud Mail), will have all content wiped from the iPhone—iOS Mail removes all emails and folders listed and created under the account. In other words, you’ll no longer see messages in the Mail app.
Deleting an Email Account From the iPhone Doesn’t Delete the Account
When an email account is deleted from an iPhone, the email account and address remain unchanged. You can still receive and send emails on the web or in other email programs set up to use the email account.
Deleting an Email Account Doesn’t Delete the Emails From the Server
For IMAP and Exchange accounts, nothing changes on the server or in any other email program set up to access the same account. iPhone Mail stops accessing the messages and folders, and you are no longer able to send email from the account using that app. Nothing changes for POP accounts either.
Deleting Calendars and Other Features of Your Account
Deleting an email account from an iPhone also removes calendars, notes, to-do items, and contacts that use this account. If you want access to those features, disable only the email for that account.
