It is possible to disable the calendar, email from syncing (for now).
Settings -> email+accounts -> Microsoft Account -> change the hostname settings to: 127.0.0.1
Calendar will stop syncing, no more emails from the MS account.
BUT all of the Office apps still sync even with this in place; Excel, OneNote.
Irregardless, if all else fails, login to the Microsoft account on your PC, change the password (and don't update it on your phone). That will kill ALL sync capabilities.
It will also disable your ability to use the app store, so you may have to frequently change your password if the syncing really bothers you.
I really would like to see an option to remove these apps, or options to enable/disable syncing of everything. I dislike the idea of forced syncing in a major way.
