To clear the “ghost” unread messages, do the following:
- Open Settings
- Select Mail, Contacts and Calendar
- Select the mail account that is showing the incorrect unread messages icon
- Change “Mail” setting from ON to OFF
- Press the “Home” button (the round button just below the screen) to exit the Settings app
- “Double-tap” the “Home” button to show running apps
- Press and hold on any of the running apps. These will change and show a red circle with a “-” in the upper left corner of each.
- Click on the red circle to close the Mail app (if you’ve never done this, closing all of these apps is a good battery life extender)
- Press the Home button again to exit out of the open apps screen
Open Settings - Select the mail account that is showing the incorrect unread messages icon
Change “Mail” setting from OFFN to ON - Press the “Home” button to exit the Settings app
- Open the Mail app
- After the Mail app updates, your unread messages count should now be correct
我做了以上操作后，还是会有900多份邮件，再做如下操作：
- 打开【邮件】APP
- 点击【所有收件箱】
- 点击右上角的【编辑】
- 点击左下角的【全部标记】
- 点击【标记为已读】
这样基本就 OK 了，如果不行的话，大退 APP，然后重复全部标记为已读，或者稍等几十秒打开即可解决。
