The same applies to Yahoo AttachmentsHow do I delete my Yahoo ';My Photos';. I've tried right click, highlight delete, but nothing?
Items in ';My Photos'; and ';My Attachments'; in Classic Mail are just views of the original email. Deleting the email will delete what is appearing in those folders. It shows what is in the ';inbox'; and ';sent items'; along with any other folders you created. You can delete from ';message view'; in the photo or attachment folders but it deletes the original email along with the attachments.
