the calender seems to syncronise from my w810 ok, but on checking, entries that were created on the phone, and are deleted on the phone are not always deleted on the PC!!
(However, new entries created on PC which are sync-ed to Phone then delted on the phone DO get deleted on the PC.
Also entries deleted on PC are deleted from phone on sync. Weird.)
Please update to v1.6.1. There is a sync-inconsistence in the phones. The UID's which are needed to identify the entrys are not always the same so MPE didn't find the right entry to delete. But it should be fixed in 1.6.1
