I've spend some time on a weird issue regarding recurring calendar events in Mac Outlook 2011 (version 14.3.5). In my case, I've set up a annually, recurring all-day appointment in Mac Outlook on October 8th 1970. The event displays correctly on the iPhone and Kerio Webmail. In Mac Outlook 2011 the calendar event is shifted to October 9. - 10. 2013!!
This bug doesn't occur on all recurring calendar events. Some of them show up properly at the correct date. As far as I can see it's not important how you add recurring event. Mac Outlook simply shows an incorrect date. A recurring calendar event appears correctly in Apple iCal, on iOS devices, Windows Outlook and Kerio Webmail!
What I did so far
- I've rebuilt the Mac Outlook identity a couple of times
- I've cleared the Outlook calendar cache
- I've created a new system user and did a fresh account setup using the Kerio Connect Account Assistant
- I've reinstalled Mac Outlook 2011 on a MacOS 10.7 and MacOS 10.8 workstation
- Timezone are set to UTC +1:00 Europe/Berlin on all workstations
- The Location Services is disabled.
and it still shows the incorrect date in Mac Outlook 2011!
Please use the exact date from above to reproduce this bug. I am highly interested in a solution.

Unfortunately there is no good solution for this problem, it's caused by incorrect Outlook behaviour. There is the same problem with Outlook + Exchange. I'm sorry, but we can't even make some reasonable workaround.
To explain it more deeply: Outlook doesn't handle all day events as date only, but it requires exact time when event starts (the time part of the start is significant). Then if you have recurrent event starting 1970, in the timezone where daylight saving time is present and the event occurs sometimes in standard timezone and sometimes in daylight saving timezone (like yours), it's practically impossible to count correct start time.
