Short description of Outlook Split Personality 1.0.136: If you are a busy person who wears a lot of hats, then you will love this. Split Personality allows you to manage ALL of your emails in Outlook, but allows you to choose the FROM, REPLYTO and SIGNATURE of any email that is to be sent at the time of sending it for each email. Yes, that's right. You create 'personalities' and select which one you want the outgoing email to be sent as.
