Ever since my computer illiterate boss

tried to hotsync his palm pilot with our receptionists computer, our Outlook calendar has been acting strange. Here's some of the symptoms...
When starting up Outlook calendar, it will not show all events for a day. When you leave that date and come back to it the events are all there.
You can't export the data from the calendar
You can't print the calendar events
Here is what I have tried so far with no success...
I tried a repair from the office disk with no change. I uninstalled the program and reinstalled the program and there was no change.
Is there any way to repair this problem or can someone instruct me on how to do a COMPLETE uninstall of the program, including registry entries so that the problem doesn't come back when I re-install it.
Thanks in advance for any help!
