I am unable to get a calender event I have made to reflect in my Outlook. I am using BES 4.0 and Outlook 2003.
I can make a calender event on my outlook and it will show up on my blackberry. Any ideas?

Is Wireless Reconciliation set to YES on your device in Calendar Options?

Yes

Make sure you are using Desktop Manager 4.0 with appropriate handheld apps. You might want to first try a hard reset, then reload the OS/Apps on the device and see if this improves.

Check your reconciliation settings as well to ensure that the device is setup to allow it to work in both directions.
