some emails get stuck in outbox on iPad
On my iPad Pro, and on prior iPads, some of my emails got stuck in the outbox and cannot be forwarded. 90% of emails go through without any problem, but a few end up in the outbox. I receive the error message, "cannot send mail. Connection to outgoing server is lost.". I have checked and reconnected with my email servers, checked settings, and done all the other things that have been recommended online. My problem is not that emails get lost, or disappear, my problem is that they get stuck in the outbox, and cannot be forwarded or sent.
