Affects both iPhone 12 & 16 Pro using the my same iCloud email address when sending from the Mail app. I have another email address non iCloud & I can send from that email from IPhone
mail app on both devices. I’ve deleted that non iCloud email account now but that has made no difference. I’ve tried all the suggested delete Mail app, restart, reinstall restart. What am I missing ?
iPhone 12, iOS 18
So, recapitulating;
right?
seems like an issue with your iCloud account or server connection to me, at first glance… I’ll look it up.
edit: the mails don’t end up in the outbox, do they?
Recapitulation is correct, the email does end up in the default mail outbox from both the 12 & 16 pro. Error message states: cannot send mail check settings for the outgoing servers in settings > Apps > Mail > Accounts. On clicking to this it defaults to Accounts iCloud - sync this phone - Contacts (green toggle on)
OK, thank you so much for the additional information.
So, it will not work if you open settings -> apps -> mail -> mail accounts -> iCloud and turn off “use on this iPhone”, I mean, it shouldn’t as you’ve tested it with multiple devices. So, turn off and back on… also consider checking your iCloud storage…

Important tip: try toggling “undo send” off and back on. (Apps -> Mail -> Sending section, lower end of the page)
In case this doesn’t help, you could contact apple support.
Thanks so much and after trying all of these with no luck - I will contact Apple support
Unable to send email from Mail app, able to send on browser
