There's two kinds of draft folders in Mail: one's called "Local", the other is in the Folder that mirrors my IMAP Account.
When I click on a draft mail in the latter one, it opens, but I cannot edit it. Anyway to change that?
Otherwise I'm not able to keep my draft mails synchronized
Thanks for your help
I know this doesn't answer your question, exactly, but Mail has always had problems with drafts folder store on IMAP server, at least with Gmail accounts.
When writing a new mail message, for example, Mail.app starts saving versions of it to the IMAP server's drafts folder every couple of minutes. Next thing you know you've got like 17 versions in the drafts folder, and they'll usually get cleared out when you send the message off, but then it moves those drafts to the IMAP server's trash folder. It's kind of insane. And that behavior has persisted through many versions of Mail.app.
