We are currently using Zimbra Version 5.0.6_GA_2313 on our server, and we have a few users testing Zimbra Desktop Beta2 (build 1119) as a possible Outlook replacement. Does this configuration support GAL, and if so how is this enabled in Zimbra Desktop. I have a user on Ubuntu and Vista, and both cannot access the GAL contacts, or see GAL addresses when composing new mail using Zimbra Desktop. Works fine using the web interface.
