Firstly I set up Sierra brand new and the mail.app is absolutely useless.
Ok so I decided to clear out some mail. First I had around 30MB used space as reflected by local mail storage and iCloud mail storage. After trashing around 200+ mails and moving it to trash and then clearing it, I "get account info" in the sidebar and guess what its showing me the exact same mail count as I had before deleting it. WTF?
So I close mail and re-open it again no go...
After searching I go to mail,...
Mail App trash (Sierra, @icloud) useless
