Well, the Pre Contacts app doesn't have all the fields Outlook does, and it doesn't even have categories yet. Without spending too much time on this, all the major fields sync:
Name (First, Middle, Last, Prefix and Suffix)
Multiple Phone numbers
Multiple E-mail Addresses
Web Page Address
The Pre can't tag the phone numbers to the degree that Outlook can. Pre only allows Home, Work, Mobile, Fax and Other (2,3,4..). So it looks like Chapura had to come up with a mapping during sync.
Outlook Fields that do not appear to sync:
...too many other to mention that most people probably don't use...
Pre fields that do not sync:
I'll try to post later on the Calendar, but yes, the Calendar note syncs as well...
