I have Pylon version 6.4.8.8 to synchronize Lotus Notes
server and Sony Ericsson Phone P910i which have client
version 6.5.1.3

I have the problem that when I make an invitation to others
users and request response (accept or reject).
These responses entries are not synchronize correctly on the
WEB PIM and on the phone.
Events appears continuesly from the date of the creation of
the event until the effective date of the event.
This block the future synchronization of the calendar and we
have to delete all response of the invitation in order to
continue to synchronize calendar.
