I have an email that is stuck in outbox

This solved my problem too! The combined fix 😉

Thank you so much! That solved my problem, too!

This solved my problem. Thanks paverguy!

Thank you! This has been driving me crazy and this fixed it. 🙂

TThank you also taking out the SIM card helped

Thank you so so very much indeed.

This worked perfectly.

What a relief.

Again many thanks.

Happy 2016

Worked perfectly! Thank you!

Thank you - this is the correct fix, specifically a restart after airplane mode - thanks again

This combo worked and stopped draining my battery 🙂

Perfect! This solved it for me

Slightly different:

My iPhone was trying to send a movie via email. It had a little spinner to the left of it when viewed in the iPhone's Mail Outbox, indicating that it was trying to go out. I couldn't delete that message until I did this:

1. Quit the Mail app (double-tap on Home button, swipe up on Mail)

2. Put iPhone into Airplane mode

3. Start Mail, go to Outbox (and notice that the spinner isn't there now)

4. Swipe from right to left on the problematic email. Delete button showed up and I tapped it.

I hope this helps someone.

Of course you have to take your iPhone out of Airplane mode when you've finished with this. Remember to do that.

Yes sir, I had to use the combination approach. It was necessary for me to elect Airplane mode, shut off my iPhone and then reboot.

Worked like a charm. Thanks!

I even went to the Verizon store and they told me I would have to delete the account from my phone and re-install it. Since this account is my work email, that simply wasn't an option. Its 2/29/16 and the issue has been ongoing since 2/2/16. Awesome advice and no more spinning wheel!!!

Thanks! This was a great answer that solved my problem quickly. 🙂

THANKS!! This was the solution that fixed the issue for me, on an Iphone 5S
