Sorry to keep on, but I have restarted, rebooted or what ever you want to call turning off the iPad with the button on top - about 5 times.
I have now deleted all 4 accounts on the iPad that worked per fiscally well before and re-did all of them.
All my email work on my computer PC And my android phone.
Sorry to bug you, but I do not know how to reach any apple support
Thanks for trying, but all of those suggestions do not work
