hhello dear friends,
i am using iPhone 6 Plus 64gb with latest iOS 9.3.1 and iPhone 4 with iOS 7 . With both the phone problem is that I can receive email from my official I'd but can't send email . It says incorrect user ID or password though it's sending mail with android with same user ID and password. The mail is on imap settings.
