I've just started using the Notes feature in Mail. I have created two notes. They show up in two places - in the Notes folder and in my Inbox. I don't want them in my Inbox but when I delete them they disappear from the Notes folder as well. I' sure this is a simple matter but I haven't been able to find the answer using the help resources or website.
Open Mail preferences, then click on the Accounts icon in the toolbar. Select the Mailbox Behaviors tab. Uncheck the box to display notes in the Inbox.
