Build 315 v1.1

This problem is not new, it has manifested itself with all prior versions of Mobility Pack.

Device: HTC Touch Pro II (ROM (51489) WWE)

Appointment is scheduled in GroupWise - sync's perfectly to device.
Appointment is then declined and/or deleted in GroupWise - appointment is never removed from device.

Has anybody else seen this type of behaviour either with an HTC or any other device.

Any ideas or advice on how to resolve this.
