There are a few reasons why you might not be able to delete an email on your iPhone 7. For one, the email may still be stored on the device. If it is, you can try deleting it manually by going to Settings and selecting “Delete Email.” If that doesn’t work, or if you’re having trouble deleting an email from your iPhone 7, you can try using a third-party app like Mailbox or iCloud to help you delete emails.
