I just had a go at downloading Outlook from the App Store and installing the software. I used to use Outlook, but now use Mail and Google Mail with gmail addresses.
Outlook immediately wanted access to everything! Even my gmail accounts. After about two minutes of wondering how Outlook might benefit me, I bailed.
Like you say, Jon, Mail works fine.
