I have been installed Zimbra 7 under Centos 5.5. everything is working fine I can send and receive emails.
The problem is, under outlook or any other email client we can not query zimbra address book to show users email address. But, it works fine under zimbra web interface.
from any computer I can telnet on zimbra server on port 389, that is mean no firewall problems.
any idea. Thanks in advance.
