Well at least I'm not alone! We've had the identical problem for 3 days now. Can't log on to email, get the signin1.bt.com message posted here, but can see email on my phone (I just don't like to use them there as the text is so small). We've rung BT twice, spent most of yesterday trying to sort it out cleared all our cookies and browser history as they advised, run a full virus scan, shut computer down each night (which we always do anyway), tried through Chrome and Internet explorer, etc etc etc. I've never been on this community before, but I registered having seen this thread, and of course the first thing it did was say "we've sent you an email to confirm". Aghhh. I've tried the links suggested here but no luck. But at least I'm not alone! Mind you, we've had nothing but trouble with this email since the changed format.
I shall keep an eye out for any new suggestions, but to be honest I think our best choice is to go elsewhere for our email provider.
