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