2. Continue holding the icon until it starts to shake.
3. Tap the small X that appears in the top left corner of the app.
4. When prompted, tap Delete.

6. Open the App Store.

Why this works:

It’s possible that the email app on your iPhone has been corrupted. When this happens, it can prevent emails from loading and interfere with keeping your email app up to date.

An effective way to get rid of this problem is to temporarily remove the app from your iPhone. By doing this, you give your device a new opportunity to reintegrate the app into its processing uncorrupted.

Pro tip:

This step only applies to people using third party email apps like Outlook. If you use the built-in iPhone Mail app, you can skip this step.
