Q: unsent message stuck in outbox of iPhone 6S plus

Try this : Airplane mode, restart the phone, then try to delete the mail from Outbox (or draft).

It happened to me and solved my issue.

tthx!! this solved my (recurring) problem with messages getting stuck in my iPhone 6s outbox.

Apple & the GeniusBar rep told me I had to delete my iCloud email account from my iPhone & then add it back, but that totally screwed up my mail in various ways. So when the same thing happened again, I really didn't want to use that solution!!

This solution actually solved the problem very quickly, and with no unintended consequences.

Many thanks!!

IT worked! Thank you this is the only method that worked.

Thanks so much for this answer it helped me as well too!

worked great but I had to wiggle my left big toe.

This did not work for me.  But here's what I did:

I went into settings, mail,  then into that mailbox that's having a problem,  Then outgoing mail  and turn the server off. I went back in to mail program and was able to edit and then delete that bad email.

Went back into settings and etc and turned the server back on for the outgoing mail. Tons of data used internationally, unfortunately.

Thank you, this worked!

THANK YOU FOR THIS POST! It is the only suggestion that worked for me WHEW.
