Emails disappearing from IPad
I was checking my emails on the IPad last night (TalktTalk account). I noticed there were 4 new ones but couldn't open them, then they all disappeared - opened and unopened ones. Not in the trash. Checked the account today on the PC - none of the ones I noticed last night were there. There was one email I particularly needed to read - anyone got any idea of what went wrong and what I can do to put it right?
