Why doesn’t my iPhone say out box in my email it only says sent

Hi Dawn6973,

Thanks for posting in Apple Communities.

We understand that you want to see "Outbox" mailbox. This is expected behavior. Outbox only shows when an email was not able to be sent. It then goes to your Outbox. Since your emails have been sent, they are shown in Sent.

You can read these details in If you can’t send email on your iPhone, iPad, or iPod touch.

Regards.
