Question: iphone and ipad not recognizing mail
11/11/17 This problem happened overnight - email was coming through just fine last night on both iPhone 6 and iPad Pro devices and this morning I cannot send or receive email, says my account is not recognized. Have gone through all the steps to delete account etc. and the problem remains. No settings were changed on either device and the software is up to date. Have tried resetting phone etc... any suggestions? This is extremely frustrating as my non Apple devices do not have this problem so I know this is all Apple related.
iPad Pro Wi-Fi, iOS 11.1
