Deleting "error" emails

I have several emails that had errors and were never sent. They show up on the “Operations” panel under the “Errors” tab. I don’t need these emails any longer and I’m wondering how to get rid of them. Thanks!

You will find the message in the Local Folder Outbox. If Local Folders are not visible below your other folders, you can enable them by selecting Menu > Settings > General > General > Show Local Folders.

Thanks, Gary. I have local folders enabled, but the icon is grayed out and no messages show in any of the local folders, i.e., Inbox, Outbox, Sent, etc.
