        Hi,
after some investigation of the server behavior and the EWS protocol,
the protocol requires both Start and End times being stored as
xs:dateTime, which means using both the date and the time for the
event, though the iCalendar component itself doesn't hold this
information, thus the evolution-ews stores the times in the default
time zone, which is UTC. By editing the event in the OWA interface the
timezone is updated to the one which is set in the OWA, thus it
"fixes" the event.

The definition of the All-Day event is also different in the EWS than
in the Evolution, they mean with it:

   An all-day event spans the duration of working hours that is
   defined for a mailbox.

which is truly not an all-day (whole-day) flag as the Evolution
understands it.

I filled bug [2] for a reference.
        Bye,
        Milan
