Removing a Yahoo Mail account from an iPhone running iOS 9 deletes that account’s connection from the Mail app; it does not delete the Yahoo account itself. Messages stored on Yahoo’s servers remain available when you sign in through Yahoo or add the account to another device.
Remove the Yahoo account from iOS 9
- Open Settings.
- Select Mail, Contacts, Calendars.
- Tap the Yahoo account you want to remove.
- Scroll down and choose Delete Account.
- Confirm that you want to remove it from the iPhone.
“Delete Account” here means remove it from the device
In this Settings context, the button removes the configured mail account from iOS. It does not close your Yahoo identity or permanently erase the mailbox from Yahoo’s service.
Check locally stored information before removal
Mail using IMAP is generally synchronized with the server, but contacts, calendars, notes, or other account data can also be connected to the Yahoo account. Verify important information is synchronized or backed up before removing the account.
If you want to close Yahoo permanently
Use Yahoo’s current official account-termination process in a browser. Permanent account deletion has consequences beyond iPhone Mail and can affect messages, contacts, account recovery, and other Yahoo services.
iOS 9 is obsolete
Modern iPhones use Settings > Apps > Mail > Mail Accounts or a similar current path rather than the iOS 9 menu. Devices limited to iOS 9 no longer receive current security updates and may not support modern Yahoo authentication reliably.
If the goal is simply to stop notifications, disabling Mail or notifications can be less disruptive than removing the entire account.
