Using New Outlook on Windows for professional communication and productivity
It looks that we have no choice but to find a substitute for Mail if we don't like Outlook. I have tried Thumderbird but I find it quite slow to open and doesn't manage Outlook calendars. After some search and experiments, I finally found Wino Mail which looks very much like Mail (and VERY FAST to open!) and One Calendar which is very fast too and very convivial. And both are FREE !
