[Q] Sync with Kies gone bonkers

After updating my Samsung Galaxy 10.1 to ICS 4.0.4, KIES doesn't synchronize my appointments found in MS Outlook to the tablet.

Appointments entered from the Tablet are synchronised with the MS Outlook.

Model No: GT-P7500
Android Version: 4.0.4
KIES version: 2.3.3.12085_7

Previously working under stocked Gingerbread version.
