Blackberry/Outlook are always synched and appearing on my Outlook Calendar?

I have a Blackberry which I am syncing with my Outlook. I have no problems in getting them synced. However, meetings that I enter in the Blackberry do not appear on Outlook. But if I add a word or letter in the appointment that I entered in the Blackberry, then save that appointment, it appears in my Outlook.
I am using Blackberry Desktop Manager (BDM) to sync. How can I make sure that all my meetings, whether entered in the Blackberry or in Outlook are always synced and appearing on my Outlook Calendar?
Thanks for your help.
