Had a problem with my mail app not updating, after trying loads of solutions I opted for a 'clean boot'. This solved the problem apart from the live tile showing a month old email. None of the start-up programs appear to be causing the problem and the app is working fine back in normal boot-up. Couple of questions - is there any point trying to find out what caused the mail problem in the first place? And what can I do about the apparently stuck live tile? Many thanks.
