Comment 12 for bug 115913

I noticed the same issue on my xperia (wm 6.1).

After reading through all the comments here I played around a little with the sources of the
exchange plugin. I noticed the following lines (calendar/e-cal-backend-exchange-calendar.c):

 /* OWA seems to be broken, and sets the component class to
  * "CLASS:", by which it means PUBLIC. Evolution treats this
  * as PRIVATE, so we have to work around.
  */
 prop = icalcomponent_get_first_property (icalcomp, ICAL_CLASS_PROPERTY);
 if (!prop) {
  prop = icalproperty_new_class (ICAL_CLASS_NONE);
  icalcomponent_add_property (icalcomp, prop);
 }

I just commented out those lines (from prop to } ) and after the installation and an restart of evolution
activesync started to sync and showed to sync one event. But the activesync screen didn't show 'processing'
then and the event wasn't in the calendar. (But, of course, in OWA)

Hope we can get some steps further from this.
