I THOUGHT it worked at one point, but now it doesn't.  I am getting the
timezone error.  The TZID is being set by the remote Exchange server and
not being handled by Horde.  Same calendar event works to gmail/yahoo,
but Horde complains:

Unknown or bad timezone (Pacific Standard Time)


So, three parts are mime-encoded in the Calendar request sent from  
Outlook though an Exchange server.  There is a .calendar file, a .html  
file, and a plain file.


The calendar request has:

BEGIN:VCALENDAR
METHOD:REQUEST
PRODID:Microsoft Exchange Server 2007
VERSION:2.0
BEGIN:VTIMEZONE
TZID:Pacific Standard Time
BEGIN:STANDARD
DTSTART:16010101T020000
TZOFFSETFROM:-0700
TZOFFSETTO:-0800
RRULE:FREQ=YEARLY;INTERVAL=1;BYDAY=1SU;BYMONTH=11
END:STANDARD
BEGIN:DAYLIGHT
DTSTART:16010101T020000
TZOFFSETFROM:-0800
TZOFFSETTO:-0700
RRULE:FREQ=YEARLY;INTERVAL=1;BYDAY=2SU;BYMONTH=3
END:DAYLIGHT
END:VTIMEZONE




The .html component has:

<div>When: Wednesday, January 09, 2013 4:00 PM-4:30 PM (UTC-08:00)  
Pacific Time(US & Canada).</div>

The plain part that has:

When: Wednesday, January 09, 2013 4:00 PM-4:30 PM (UTC-08:00) Pacific  
Time (US & Canada).



Seems like Kronolith is reading the calendar part of the attachment  
and balks on the the TZID included by Exchange.
