I am using Outlook 2007 and I also sync it to my blackberry using Rim's
Desktop manager v4.7.

For some reason when I put in a new appointment, in Outlook, it adds 2 to 8
minutes to the appointment. So a 2:00 - 3:00 appointment would actually go
into the calendar as 1:58 - 3:00 or maybe 2:04 - 3:02. The minutes added are
always even.

Then it won't let me change the appointment. I get an error message about
it not being recurring and to close all open items. But the appoointment is
not recurring.

I have been syncing for years and never had this problem but it stated about
20-days ago. I've tried deleting all the data and reloading.
