I'm using Outlook 2003 and this is happening to me too. It started when I got
a BlackBerry and also synching Outlook with Google calendar. Older items are
deleting from Outlook calendar. Then I get a message from Google Calendar
Sync: "Google Calendar Sync has detected that you have deleted 21 items. This
will delete 21 events from your Google calendar. Proceed with operation?"

I'm not deleting, not autoarchiving, not finding any items in the Deleted
Items folder nor the Recycle Bin.

I am running Office 2007 on Vista.

Please help, alot of my appointments have started deleting off my
calendar.
I have been syncing with my Blackberry bold and have checked all the
setting
and cant figure out why the appointments are deleting off the PC calendar
because they are still currently on the calendar in my blackberry.
