Blackberry - Calender not syncing on BES

Here is an issue I dealt with today. A user’s blackberry wasn’t synchronizing properly. Messages came through fine but not calender items. A check of the BES server showed everything fine in terms of settings. Here was the resolution, go into the blackberry, into calender, into options. Look for wireless synchronization, make sure it’s on, if it is on, turn it off, pull the battery. After you boot it back on, turn the wireless sync back on. Hope this helps.
