I have an iphone 4 which has suddenly stopped working for my email box. I go to it and it says: no mail, then it comes up and then it goes back to home page. Can anyone advise?

Hey jenjnash,

If I understand you correctly, when you open the Mail app on your iPhone, it shows no mail and then the app quits and takes you back to the home screen. Is this right?

You may want to try some things to troubleshoot -

First, quit all running applications and test again -

Force an app to close in iOS

Next, I would try restarting the iPhone -

Restart your iPhone, iPad, or iPod touch

If the issue is still present, you may want to restore the iPhone as a new device -

Thanks for using Apple Support Communities.

Happy computing.

Jen,

Try resetting your Mail Account and system by following these steps. Please do not skip any steps. First close your Mail App completely from the multitasking window by double clicking the Home button and swiping up the Mail preview pane up until it disappears from the screen. You may have to look for the Mail pane by swiping side to side as there may be other panes there from other apps. Then go to Settings > Mail, Contacts, Calendars > locate your email provider and click on the account. Then on the next page Delete Account. Then do a forced restart. Hold down the Home and Wake/Sleep buttons at the same time for about 15-20 seconds until the Apple logo appears. Ignore the "Slide to power off" text if it comes up. You will not lose anything. Then go back to Settings > Mail… and add the account again.
