We are moving from Exchange to an IMAP server. Is there a way to have a global address book in Outlook without exchange. I read on an Internet post a response to this question which said, "You could create an LDAP query yourself if your client/server supports that and that would accomplish the same thing." There was no elaboration.
We are running a Samba4 Domain Controller / Active directory so LDAP is available, but beyond that I'm clueless about what to do.
