Email account deleted and 2.69 GB still showing up I deleted my email account on my iPhone 6 because it has 2.69 GB of mail and attachments. The 2.69 still shows up with the deleted email account. What can I do to regain the storage?

I also rebooted the phone. It acted up when I shot an 11 minute video and tried emailing it.
Have you checked your Drafts folder? The email draft with the video attachment should be there. Try to delete that specific email draft.
