Outlook features sync with iPhone

I use four main features of Outlook and these are the Calendar, Contacts, Notes (which are also called as “Memos”) and Tasks. My question is; will all of these features sync with an iPhone? I thought I heard that iPhone does not allow Notes/Memos to be sync. I even heard that maybe the Tasks part does not also sync with iPhone. If those parts do not sync with an iPhone, are there any applications that allow these parts to sync?
