+1 for Martin's delete/undelete tip. That has worked for me in the past. Tom

I have not had the problem reappear after this and the end user can do this themselves. This works for calendar as well. Just change part 2 to calendar rather than address book. You can try the steps below to see if this resolves the issue. 1) Ask the BlackBerry smartphone user to delete the Desktop [SYNC] service book from the BlackBerry smartphone, then undelete it by completing the following steps: a. On the Home screen of the BlackBerry smartphone, go to Options > Advanced Options > Service Book. b. Highlight Desktop [SYNC], display the menu and click Delete. c. Confirm the delete before exiting the Service Book option. d. Navigate back to the Service Book option, display the menu and click Undelete. Warning: The following procedures will delete either all data, or all data and applications on the BlackBerry smartphone. Back up the data prior to performing the procedure. For instructions, see KB12487. 2) These steps only apply to BlackBerry Device Software 4.5 to 4.7. To delete the data in the Address Book application over the wireless network and reload it from the BlackBerry(r) Enterprise Server, complete the following steps: a. On the BlackBerry smartphone, open the Address Book application. b. Display the menu and click Options. c. Type RSET. Note: For BlackBerry smartphones that support SureType(r) technology, use the multi-tap input method. If wireless synchronization of the Address Book application is turned on, the following message will appear: This will erase your Desktop address book, and reload it from your server. Continue? After the data in the Address Book application has been deleted, the following message will appear: The Desktop address book has been wiped. It will be repopulated from your server. The Address Book application will be re-populated with Address Book data from the BlackBerry Enterprise Server and the following message will be displayed: Repopulation of the address book ~ Finally, powerful endpoint security that ISN'T a resource hog! ~ ~ <http://www.sunbeltsoftware.com/Business/VIPRE-Enterprise/> ~
