Have tried all types of turnoff and the App is not deletable.
Like this ... Settings>Mail, contacts>Calendars>Gmail account>Mail>Off. Restart the iPad and then go back to
Settings>Mail, contacts>Calendars>Gmail account>Mail>On and try again.
iOS: Unable to send or receive email

Or this - Delete the account in Mail and then set it up again.

I have tried all the suggestions above, but the accounts wont delete and the app crashes on both my iphone 5c and my wifes ipad mini, this has only happend today and we can access our mail from a web page or PC we use exchange server mail and hotmail and they both seem to be dead. I restarted the iphone while it was attempting to delete my accounts, which strangly lets me open the mail app, but i just get the searching for mail thing and nothing else. hope someone can advise, i have automatic updates set so this maybe as a result of an update i'm not sure for info i'm running the very latest ios7 in the UK
