Delete And Reinstall The Mail App

1. Press and hold on the Mail icon until the menu appears.
2. Tap Remove App.
3. Tap Delete App to confirm.
4. Open the App Store.
5. Tap the Search tab in the lower right-hand corner of the screen.
6. Type in “Mail” and tap Search.
7. Tap the installation button next to Mail.
8. Head back to the Home screen and tap on the Mail app to reopen it.

Why this works:

Deleting and reinstalling an app can fix a persistent software problem. It’s possible a file within the app has become corrupted. It’s easier to just uninstall the app rather than attempt to track down the root of the problem. The Mail app will be just like new after you’ve reinstalled it.
