In the past, calendar sync problems for me have always been related to multiple calendar service books that exist for each of your email addresses, as well as for facebook. The way I have always solved this problem is to go to options>advanced options>service books and highlight, then delete ALL service books that end in CICAL except for the one that is the same as your primary email address. Then try to resync.
I'm assuming that you have set up (configured) the sync function in DM.
