BT mail worked fine on my i Phone and PC but NOT on the i Pad.
I can only assume that there may have been a corruption in the i Pad mail app.
I had same thing tried everything, deleting accounts, adding again, turning off ipad numerous times.
Solved the issue by simply deleting the 'Mail' app and reinstating from the app store ..
re-entered email and password and away it went fine.
