I've just logged into my BT account on my PC (I've been checking it on my phone for the last few weeks) and found that all of my emails, other than ones from the middle of May or sooner, have been deleted. I've had the account for two years, so that's two years worth of emails lost.
Fortunately, there's not really anything of much importance (although a mark scheme for an exam paper that I need for revision would be useful!) and they should be on Outlook, but it's annoying.
Has anyone else had the same problem and does anyone know if I can get them back?
