I just installed Zimbra Outlook Connector It was very simple, but I am having problem with contact sync.

here is the detail:

After I installed the connector and created the profile, I import my contact and calendar entries from my old PST file. Both calendar and contact are showing fine in Outlook 2003, but only calendar events made to my Zimbra web account. Address book is still empty. If I add an entry from Zimbra web, it will show up in my outlook, but any changes to that entry will NOT sync up to the web account, even deletion.

What did I do wrong?
