Good evening,
unfortunately, there's a bug in Zarafa Webaccess where a bugfix advisory has been made available by Zarafa:
Recurring meetings one hour early between 25 Oct and 31 Oct ===========================================================
Description: Recurrent meeting requests starting between 25 and 31 October 2010 are one hour too early in calendars.
Zarafa Versions affected: Zarafa 6.30.x and 6.40.x
Issue: The issue occurs only if all of the following conditions are met: - Timezone Europe (CET) - A recurring meeting request is sent to attendees - The first occurrence of this recurring meeting request is between 25 and 31 October 2010 - In spooler.cfg always_send_tnef is set to no (default)
Result: The attendees see the appointment one hour too early in their calendars. Unfortunately there is no easy workaround to fix these meeting requests other than manual adjustments.
Workaround: In spooler.cfg configure: always_send_tnef = yes
Fix: This issue is analyzed and fixed. The fix will be available in version 6.30.18 and 6.40.4.
Issue date: October 21th, 2010
Fedora as a downstream will perform an update to the next stable Zarafa release (6.40.x), once it is available.
Greetings, Robert
