Sorry for butting in but I've recently done this, the new Gmail compose "experience" was the final straw. I'm happy - the only thing that is a bit weird is I'll sometimes get spam mails duplicated arriving at my outlook.com address. Never with "normal" mails only the obvious spam. Does anyone know of an easy way to extract all my mails from Gmail? I'd like to dump them in the filesystem and then kill my Google account.
