I have configured multiple domains in my Zimbra server. In the web UI, users can share calendars, e.g. email@example.com and firstname.lastname@example.org can share their calendars with each other.
However, using Outlook and ZCO, email@example.com cannot open the calendar of firstname.lastname@example.org because email@example.com is not in the GAL list (well, at least I think that is the problem).
firstname.lastname@example.org can open the shared calendar from email@example.com without problems.
Am I doing something wrong?
How can both users share each others agenda using Outlook?
My version is 4.5.0.
