I am sure that this problem was asked before. We have two domains. One is google apps and the other zimbra network edition. Thing is that we would like to have write-ahead email addresses. The same thing that happens for the users in zimbra via contact sharing. We want the same for all our users in google apps in zimbra.

So if Tom Apple is an user in google apps, and I type in Tom in the TO field of Zimbra, I get the email address of Tom Apple.

How can one do that? I don't want to create an user Tom Apple in Zimbra, that will cost me a license.

Thanks for reading,
Tom Apple
