Busy Time Events Change to Free Time

I have two recurring all-day events on my calendar in OL2003. The events
occur for four straight days every other week (basically my work schedule -
I
work Tues to Fri one week and Wed to Sat the next). In the options for the
series, I set up the time to be marked as Busy, so that it will show up on
monthly views of the calendar as a day containing an event. I do synch my
calendar with ActiveSync to an IPAQ and back to another computer running
OL2007.

For some reason though, these two recurring events frequently lose their
Busy status and revert back to Free. I do not change the status at any time
on either PC or my PocketPC. Does anyone have any ideas about this? Is there
something I am doing that inadvertently changes the Busy status?

Thanks,
Merg
