Zimbra Address Book shows repeating contacts
I have configured Zimbra to use External Global Address List from Exchange.
When I type "*" to search from Global Address List on the Address Book Tab, it shows 100+ contacts.
When I scroll down, the address book shows repeating contacts of the previous 100 contacts. I continue to scroll down, Zimbra shows more than 1500+ repeating contacts, but we only have around 700 contacts.
When I create new email and click <TO> to select addresses, the address book still shows 100 same contacts even I click <Next> and <Next>.
Is this a bug or I have configured wrongly?
But the web access shows all the contacts correctly.
